Very small, lightweight, and with good brightness. Don't expect a projector, but it has good lighting. I have put it on my keychain to take the dog for a walk at night. A worthwhile purchase and durable

A good lens from Fenix... Good build quality, very convenient size and lightweight to put it on your keys. I usually prefer twist on-off lenses like this one. I consider them more suitable for tough use and dirty hands. Aluminum A6061-T6 with HAiii type anodization.

It has a nice beam of light, perfect for an EDC lens. Overall, I consider it much better than the competitor Olight i1r. I like that it has a charging indicator, meets waterproof and dustproof specifications (IP68), is resistant to drops, and has a glass with a reflective coating on the head instead of plastic, for example. The moonlight first level suits him because it is not as weak as others and is also economical in terms of consumption and therefore duration.

Ideally, I would like it to be tailstand and the screwing-unscrewing of the head to be a little tighter so that it does not unscrew in pockets and collect any debris. You need to check it from time to time. I think this can be fixed with a thicker o-ring. It is important that you won't lose the head even if it completely unscrews, because it does not separate from the body of the lens.

It is in the dimensions of keys and quite bright. The rechargeable battery is very convenient. I would prefer USB-C instead of micro USB.
