It is ok, but there are better features on brands a third of the price. - Cloud Defensive REIN 3.0 Full Size Weapon Light

Bright and feels light yet sturdy. The features are fairly intuitive. It doesn't come with instructions and you will have to find a third party reviewer/unboxing if you have issues because Cloud Defensive's instructions are horrible. The manual on Cloud Defensive's website has no pictures and there isn't much in terms of useful videos on their website or YT page. You'll probably be all right if you owned one of their previous versions. The tail cap can be adjusted so the cord comes off at 90/180/270/360. The switch is fastened on with two pieces of plastic onto the picatinny. Over $300...it shouldn't have any plastic for mounting. Also, it is quite a bit larger than other weapon lights. There is only the attachments for a pic rail (not included) and the aftermarket torrent mounts run around $40 for MLOK. Overall, I am unhappy with it enough to not buy it again, but happy with it enough to not return it so it gets 3 stars.
