Came nicely packed and with easy to follow instructions...the screw in tail cap was very snug but with the o ring washer, water doesn't stand a chance...like the brightness levels and very bright red led and uv for money and pet fluid checks, a little heavy for key chain carry, 1,000 lumens on 10440 and still very respectable on AAA.......heats up fast at high setting but most small lights do ..all in all a nicely thought out Swiss army knife concept kind of light for your pocket..not perfect but very useful.....

What to say about Acebeam. ""An Excellent Manufacturer" is there on the instruction sheet. Well I'm going to disagree here not because they make poor products but because they make gimmicky products. A simple key light that has 10 modes buried under the single button for the user to decipher. NOT user friendly (you really have to read/decipher the instruction sheet)... 2 stars because it is bright but good luck trying to find that turbo mode especially if you need it quickly. It uses 2 AAA batteries in parallel (or 2 of the higher voltage 10440 Li-Ion) which I guess is an advantage as other very bright key lights have non-replaceable batteries. It does make the light about 30% heavier but who's counting. Also disappointing is the IPX 54 rating. "Splash resistant" so if you have it in your pocket and fall into a pond or surf you probably can kiss it an expensive goodbye.
No lanyard (and shouldn't put one on) but you can attach a separate removable pocket clip (2 hex-head screws). The screw that you could use to put a lanyard or key ring on also secures the battery compartment cover. Not a good idea because you can inadvertently untwist the screw and the cover with the batteries will fall out leaving the light completely useless.
