Reviews FNIRSI SAG-55

Authentic Feedback Analysis:
⭐ 5.0/5 | AliExpress Shopper (UA): 20 air flow modes, temperature adjustment from 100 to 450 in steps of 5 to 25 degrees. Very excellent heat gun.
⭐ 1.0/5 | s***i (GB): After waiting for more than 3 weeks. It was such a disappointment. As soon as I turn on the heat gun it started having burn, fire and smoke inside. Without a single use item got broken and body started melting.
⭐ 5.0/5 | Д***ч (RU): All good!
⭐ 5.0/5 | F***n (NO): Amazing product! Perfect seller! Fast shipping! Great communication! High quality item! Takes less than 10 seconds to heat up to 300c!! Love the auto standby function when you put it on the stand. Get one, you won’t be disappointed 🤩
⭐ 5.0/5 | s***r (BG): As always high quality product!
⭐ 5.0/5 | s***g (GB): Awesome bit of kit. It’s a shame that there’s no UK plug option. As described, well packaged and fast delivery. Many thanks.
⭐ 5.0/5 | AliExpress Shopper (IL): Awesome!
⭐ 5.0/5 | AliExpress Shopper (PL): Very nice equipment, just right for my amateur needs, well packed and quickly delivered. I recommend it.
⭐ 5.0/5 | w***r (PE): Quite good, I use it often and I am very satisfied with the purchase.
⭐ 4.0/5 | S***i (IT): Little to say. To try but everything seems ok like all products of this brand.
⭐ 5.0/5 | C***s (US): Best heat gun I’ve ever used.
⭐ 5.0/5 | A***a (ZA): Best hot air gun ever and more advanced but the only thing that disappointed me is being lazy to write a full address of mine which made my parcel to get lost at first.
⭐ 5.0/5 | U***n (DE): I’m satisfied so far👌
⭐ 5.0/5 | V***v (BG): Brand+++
⭐ 3.0/5 | M***i (BR): Arrived intact, now to test it, then I will return with my final considerations.
⭐ 5.0/5 | J***r (HU): Compared to the weak and buggy quality of the Fnirsi brand, this is quite good. Out of the 12 Fnirsi products I have purchased so far, this is the fourth one I am satisfied with. It is not good for small diameter nozzles, the fan cannot pump enough air, but it can be used well above 6-8mm. I have not tried it with a nozzle larger than the tube size, I do not have one.
⭐ 5.0/5 | Z***k (PL): Works well, maintains constant temperature. I can recommend it.
⭐ 2.0/5 | AliExpress Shopper (AR): The equipment arrived after 90 days and with faults. I was able to fix the defect of the equipment. Communication and attention with the seller was good.
⭐ 5.0/5 | AliExpress Shopper (PE): The product arrived in good condition, it was not very protected but fortunately it arrived without physical damage, the equipment works well except for the metal stand, it seems that it does not have the magnets (or they are defective) that activate the sleep mode of the gun. I contacted the store and they quickly attended to the case, after some tests placing magnets around the gun I discovered that the gun does detect the magnets so the problem is in the metal stand. The store confirmed the problem and gave me a partial refund (I am satisfied since the gun works almost entirely except for the sleep mode when placed on its metal base). I would say that it is a somewhat minor problem that does not affect the functionality of the gun but they took it very seriously. First time a factory defect has occurred to me but it was resolved in a good way. I recommend the store, I have been buying many products of the brand since the beginning of the year and they continue to work.
⭐ 5.0/5 | AliExpress Shopper (CO): The product looks good quality, works correctly, took 15 days to arrive in Colombia.
⭐ 5.0/5 | AliExpress Shopper (ES): The product looks very good but they sent it to me through Correos and charged me €190 for delivery where they send me the rest of the orders by GLS, DHL or Correos Express.

⭐ 5.0/5 | J***j (CZ): Good quality.
⭐ 5.0/5 | AliExpress Shopper (SA): Great hot air gun, but one small annoyance is that the fan makes an annoying whine while it’s in sleep mode. But aside from that, everything works perfectly.
⭐ 5.0/5 | s***a (HR): Great product works like a charm.
⭐ 5.0/5 | AliExpress Shopper (IL): Great Thermophene!

Regards.
⭐ 5.0/5 | S***s (US): Honestly, I’m impressed, I was expecting a good tool but with some temperature issues but for my surprise, is powerful enough to work in a pcb as a ps4, that’s big.
⭐ 5.0/5 | AliExpress Shopper (UA): I absolutely love this one.
⭐ 5.0/5 | j***j (CZ): I am extremely satisfied with the product and the store. Everything works, exactly as described, everything looks high quality and the package arrived perfectly packaged within a few days. What I have to highlight to the heavens is the communication and willingness of the FNIRSI store, they willingly and friendly helped me resolve the order I had chosen incorrectly. I definitely recommend it and I will be happy to shop in this store again.
⭐ 5.0/5 | I***h (UA): I have tested it — in my opinion, it works really well. I was worried about the ergonomics, but it’s easy to operate and handle. The pro stand looks really solid, but the standard one is way more compact, which might be an option for someone.
⭐ 5.0/5 | AliExpress Shopper (GH): I really love this product very much and I recommend 👌
⭐ 5.0/5 | P***s (GR): Is a professional tool I am very satisfied.
⭐ 4.0/5 | AliExpress Shopper (AU): It’s pretty good but would be even better if it came with more nozzles. The included one is too small for larger components, had to remove the nozzle altogether. There was also no option for the AU plug. That said it heats up quickly, holds the temperature and the stand is high quality. Good value for the price.
⭐ 5.0/5 | Y***n (DE): It’s worth the money, very good.
⭐ 5.0/5 | N***a (GT): Arrived in excellent condition, arrived earlier than estimated. I already used it and it exceeded my expectations, it has wind speed adjustment mode, adjustable temperature, perfect for working in different conditions. I was very satisfied with the product.
⭐ 5.0/5 | 4***r (CO): Arrived very fast, well packed, I have tested it and it heats up super fast and the temperature is sufficient to remove any chip and shielding. Excellent purchase.
⭐ 5.0/5 | S***a (CO): Arrived super fast, excellent product, I waited for it eagerly, I already tried it, the best and portable.
⭐ 5.0/5 | J***y (CZ): Looks very well, works very well too. Magnetic stand, extensive settings, sleep mode when placed in the stand. It’s a shame that replacement nozzles aren’t sold.

⭐ 5.0/5 | AliExpress Shopper (ES): Works perfectly on the first tests.
⭐ 5.0/5 | AliExpress Shopper (PL): Everything as it should be, fast delivery, very well secured goods.
⭐ 5.0/5 | P***k (PL): Everything is in the best order.
⭐ 5.0/5 | S***k (UA): I liked everything very much. I bought it during the summer sale, I wanted an ohm meter but I need everything.
⭐ 5.0/5 | A***j (UA): Everything according to the product description, the stand is massive, unfortunately only one nozzle is included. Everything works clearly, the heat gun is made qualitatively. Delivery was a bit delayed because they were waiting for the product to arrive, but this is not critical for me.
⭐ 5.0/5 | AliExpress Shopper (UA): Everything works. Arrived quickly.
⭐ 5.0/5 | R***t (UA): Everything arrived safe and sound. It works.
⭐ 5.0/5 | M***o (UA): Everything works great. At first I thought they sent me a defective product, I couldn’t turn it on for a long time. It turned out that it turns on with the blue button without backlight, and I tried to turn it on with the button that has different colored backlights.
⭐ 5.0/5 | O***n (UA): Very good, very fast.
⭐ 5.0/5 | M***m (UA): Convenient and high-quality tool. The brand’s products are pleasing for their price. The functionality fully corresponds. Heats up quickly. The interface is intuitive. Cons: has an unpleasant sound of minimal engine speed in standby mode and an impulse squeak of the power supply when adjusting brightness from 4 to 8. The quality of the 6 mm nozzle (outer diameter) is also high. I recommend it!
⭐ 5.0/5 | M***v (UA): Perfect, the only thing is I would like more nozzles).
⭐ 5.0/5 | Т***ч (RU): As always, the seller is famous for quality goods, no complaints, honestly sent the goods, received on time.
⭐ 5.0/5 | K***r (KZ): Excellent quality, everything as described. When turned off and placed on the station, the heat gun purges, I set it to 70 degrees in the settings, this is the minimum. I would like a couple more nozzles, one is certainly not enough. Otherwise, everything is fine. ) It took a long time, as the seller asked to wait, there was no product in stock, it’s not difficult — I waited. ) Thanks to the seller!)
⭐ 5.0/5 | v***r (EE): Well done !!! The stand is great along with the heat gun. Functionally, everything is simple and convenient. Any nozzles fit on the screw (850 series), which is a plus, since there are about thirty different caliber nozzles from old soldering irons available. The airflow is slightly stronger than the Lukey 868. So far I’m happy with everything! The advertising poster describes the fan as an intercooler type, but in reality there is a 12-volt snail fan inside. Strange feeling. In general, I’m getting used to it. FNIRSI — Pleased. Thank you.
⭐ 5.0/5 | V***o (BY): Excellent heat gun. It’s a pity that only 1 nozzle is included.
⭐ 5.0/5 | R***v (BG): Seller is great, I recommend!
⭐ 5.0/5 | З***ч (RU): Works. As always with Fnirsi, everything is well fitted, pleasant to hold.
⭐ 5.0/5 | AliExpress Shopper (UA): I recommend, I recommend.
⭐ 5.0/5 | V***d (IL): Thanks to the seller for fast delivery of well-packaged, undamaged goods. The soldering heat gun works according to the description on the seller’s page. The manufacturing quality is impeccable, as with all FNIRSI devices I have purchased previously. I only changed the power cable to a more flexible one with an Israeli plug, as the ground pin is electrically connected to the metal heating nozzle.
⭐ 5.0/5 | I***z (UA): Thank you, I received the heat gun safe and sound (although the carrier wrote that the parcel was damaged). I haven’t checked it yet, but I think everything will be fine, I checked the heat gun — it works as it should. I recommend this store to everyone. The seller is a very good and decent person. The heat gun is beyond all expectations.
⭐ 5.0/5 | V***B (UA): Super.
⭐ 5.0/5 | M***k (UA): The product matches the description. At first glance, the product quality seems good. A big drawback is the lack of nozzles, even the cheapest heat guns come with several nozzles in the kit.
⭐ 5.0/5 | AliExpress Shopper (UA): The heat gun is worth its money. Convenient. The seller is communicative and helps with misunderstandings. I definitely recommend the product. I would like more interchangeable nozzles.
⭐ 5.0/5 | AliExpress Shopper (UA): The heat gun is accurate, easy to control, the stand is just super. I would like more nozzles in the kit, but this is a trifle, otherwise everything is super. Shipping and delivery are very fast, thank you very much to the seller!
⭐ 5.0/5 | A***a (UA): Excellent quality! It’s immediately clear that this is a quality item!!
⭐ 5.0/5 | AliExpress Shopper (RU): I thought that all hot air guns are simple and not very convenient to operate. But FNIRSI made a really cool hot air gun. It is simple and easy to operate, and also has extended functionality. I recommend it.
⭐ 5.0/5 | AliExpress Shopper (AE): Excellent and practical device, and its price is suitable.
⭐ 5.0/5 | a***r (KR): Very easy to use. Can do many tasks that cannot be done with a soldering iron.
⭐ 5.0/5 | AliExpress Shopper (KR): I bought it really well. 72,000 won is not a small amount, but I really like it. It didn’t work well on the first day, but it works really well from today. I set channel 1 to 300, channel 2 to 380, and channel 3 to 430 degrees.
⭐ 5.0/5 | 6***r (US): It’s good, it would be even better if there were more types of nozzles!
