DOTSOG Diving Flashlight,3600 Lumens Underwater Scuba Flashlight, Underwater 80M Flashlight for Diving Activities, Torch Light with Rechargeable 18650 Battery

I bought 4 of these dive lights for my kids to use for night spear fishing as Christmas Presents. Their dive usually lasts no more than 1 hour. After only two trips out using these lights, one dive light battery now only lasts 10 mins. One other one now only last 25 mins and the other two lasts no more than 45 mins. Do not charge these batteries past 3 hours. Their were no directions for the batteries. I had to do a lot of research to find this. Now, being they are more than 3 months old and we just used them a 2nd time, it says I can no longer return them for a refund. Test them out as soon as you get them to make sure your batteries are not junk. Batteries are rechargeable but are also generic. Buyer beware. Do NOT buy as a primary dive light!!!

I like this from the get go, easy to turn on and off. Like the way it felt under water. It always held up well and then I did only a 53 ft dive and it looked like it was sand blasted! Paint came off everywhere, BUT I liked the "used" look. But now today on a dive, it stopped working, NO WATER damage, just stopped working. Bought it home and put the batteries in the charger and nothing! Cheap, flimsy charger from the start', and today nothing! No light, or charge. To bad, I really liked this light.

Light is not professional quality as stated.I would not recommend this light the for the following evaluation. My primary use was a dive light. I have charged it for 3 hours but light lasted 30 to 45 minutes, this might be the charger issue. The lense and bezel where the glass meets aluminium was a gap and only in time and pressure will tell if it leak. If the light is not going to be used for recreational diving and used for camping it will probably be ok. The finish anodize/powder coat was at best has minimum protection. The carrying case was a nice effort to keep things together. Stating the 3 O ring seals as quality point when it has 2 on each side makes one think they are spares. Stating aircraft and military grade aluminium, would be more believable if it was stated as T6061 or T7075. The price was way above average. I have purchased 2 and both are the same.

This dive light is a good value and good quality. I was skeptical because of the price but it per performed flawlessly on several dives on the Great Barrier Reef. Deepest dive was 25 meters and no problems with leakage. I have a couple of $200+ dive lights and I would say it performs on par with those.

The flashlight feels sturdy when you handle it, but after I took it out to the beach and snorkeled for just 15 minutes, the light started to flicker and wane. This flashlight isn't water proof, and its actually kind of dangerous that this is marketed as a dive light. Don't go out for a night dive when this is your only light. I was trying to save money, but clearly that was a bad idea in this case.

We bought 2 for diving. The light is very bright however one of the two lights got water inside but it still works. I think it leaked because it was not screwed tight. We took them in fresh water to 90 feet with four total dives so far. If you are exploring cavern openings these are great, I would not take them where I could not see surface light without a back up.

Flashlight worked ok first time in the water. Went to charge them a month later and the batteries won't charge at all. Tried 4 different chargers and none of them will charge the batteries. Very disappointed to only be able to use it one time.

Worked great but after about 3 dives started to flicker. Only lasted 1 more dives and battery charger stopped working. I tried an alt charger and got it to work one last time now will not work at.. Product is trash do not buy.
