⭐ 5.0/5 | AliExpress Shopper: Great phone, runs smoothly and it’s fast. I just wish it came with a screen protector! The plastic film that came with the phone came off when I took off the other plastic film. Now I have to use a screen protector! The speaker is pretty loud too. The strap is nice and looks good but it gets in the way of the buttons on the side. The camera is pretty good for a rugged phone. The battery 🔋 is really good, of course the phone was a bit heavy but it’s worth it. 5 stars.
⭐ 5.0/5 | AliExpress Shopper: Excellent product, fully meets expectations.
