The construction/assembly of mine may have been very poor. The plastic of the LEDs is thermally glued in exactly three points and it came off a little as soon as I held it in my hands. I had to fix it with super glue.

Good! I have it on my work keys and its magnet is very convenient. I hang them with the magnet. And sometimes I used it for some tasks that I needed light for. Of course, its battery doesn't last long, but it's okay, it's a keychain. Its price could definitely be better. Like max 2 euros.

This particular flashlight was a gift from Wurkkos, where I purchased an FC12. It is generally sold in various places under different names. Its light is a floodlight, meaning it spreads the light uniformly in the space without focusing anywhere. Also, a clarification: It is COB, not LED.
The battery so far is satisfactory for a keychain flashlight. The magnet is not particularly strong, but it does its job.
The support feet are plastic, so be careful.
I did not use it as a bottle opener, but I saw from reviews that the frame can break and become crooked after 1-2 uses.

For its price, it is the best value for money to have it with you. I would also recommend the Boruit V3, which is similar and better in my opinion, as I am the owner of both

Simple and quite powerful flashlight with 3 modes: strong, medium, and flashing. However, for about the same amount of money, I had purchased the w5130 model with 3 additional modes, a tripod, LED charging indicator, and better construction. I believed that this one would be similar - the photos are almost identical...

Very good and practical for short distances. It solves your hands with the magnet it has if you stick it on a metal construction. You can also place it as a keychain in the key set. Ideal solution for the army!!!.

Excellent tool. I am an electrician and I have attached it to my jacket. It has a magnet which is very convenient. However, do not expect crazy autonomy

It is very good and I recommend it. It has 2 levels of light, strong, along with SOS. I have put it on my keys. I don't have an opinion on the battery yet if it lasts, I recently received them. But I believe it is worth the purchase. On a foreign website, I found it much more expensive!

Very good and powerful, with two levels of brightness and SOS. It's worth its money. It is very practical and the fact that it has a magnet to stick to iron surfaces, but also a stand to stand on other surfaces, is very helpful. It charges very quickly with USB-C.
