Pros and Cons

Strengths & Weaknesses:

What I Like

Exceptional 4K video recording (3840*2160) and high-resolution 36MP camera for detailed capture.
Impressive total darkness observation distance of up to 300m (984ft) with 850nm IR illumination.
Clear and vibrant 3.0-inch HD IPS Color Screen for superior viewing experience.
Convenient 6x digital zoom and 25mm objective lens for versatile observation.
Comprehensive multi-language support and included 32GB TF memory card for immediate use.
Portable and lightweight design (265g) with a robust 18650 internal battery and modern Type-C charging.
Excellent customer service from the seller in case of defective units, as reported by users.

Points to Consider

The 6x digital zoom can significantly degrade image quality, making it less useful at maximum magnification.
Reports of the infrared illuminator being misaligned (shining off-center) requiring user adjustment.
Some units have arrived with factory defects, specifically not turning on, though seller support seems responsive.
The «BINOCULAR» drawtube specification appears inconsistent with the device’s monocular design.
The price point (around 45,000 RUB mentioned in a review) might be considered high for some users given the noted drawbacks.

Authentic Feedback Analysis:
⭐ 5.0/5 | М***ч: A miracle device, doesn’t take up space, can carry it in your pocket, works perfectly with a good power supply. There were minor issues with delivery, but the seller honestly wrote about it, for which he gets special thanks.
⭐ 5.0/5 | Е***ч: Ordered, but instead of a week (express), delivery took more than two months. Despite the seller’s logistics having a serious failure, I still received the power supply. Now about the device. It’s packaged very well. Branded box, all in foam. Damage during transit simply couldn’t happen. The capabilities are sufficient for my tasks, and I also really like compact devices. Satisfied with the purchase.
⭐ 5.0/5 | А***ч: The product is good! Personally, it’s very convenient for me to use.
⭐ 5.0/5 | Е***ч: Excellent unit… if you’re not chasing super accuracy. For operational diagnostics, etc., it’s just super. Cons: no case and no bolt terminals.
⭐ 5.0/5 | С***ч: Works.
⭐ 5.0/5 | К***ч: Normal.
⭐ 4.0/5 | С***ч: Delivery took two months instead of 10 days. The track was not monitored, the delivery service changed several times. Sent by the seller a month later, not one or two days.
⭐ 5.0/5 | Х***ч: The laboratory power supply is excellent. Everything works normally. The drawback is that the included wires — plugs do not fit into the «+» and «-» output holes. Had to use other wires. This is not critical and does not affect the operation of the source. I will charge batteries at different voltages and for other purposes. There is a current and voltage limit. Very convenient. I recommend buying it.»
⭐ 3.0/5 | Н***а: The unit does not turn on from charging applications, while the phone charges from it, I don’t understand what the problem is, it turned on with a phone charger but at 5 volts.
⭐ 5.0/5 | М***н: Excellent portable option.
