Deep Drop LED Fishing Light with Clip - Underwater Fish Attractor Lamp - 2100ft Depth - Perfect for Night Fishing, Ice Fishing & Boat Fishing

Bought this twice for it to ruin my late night plans twice. Thought it was just a defective piece at first but no two times in a row it turned out to be junk. Even if it did work as soon as I opened it I could tell it was a really really cheap product that wouldn't last regardless. At least I was able to get my refund twice.Arrived with a bad o-ring and after getting over the initial disappointment of not being able to take it out in the morning fishing I have come to realize a 10 cent o-ring isn’t a good enough reason to rate this light at 1 star. After I replace the o-ring and give it a water test I will update.I bought 3 ,used brand new batteries, but it did not work, changed the batteries but it also didn't work at all ???Took this to florida before opening to put in a crab pot by the doc for our kids. It would turn on for a split second than nothing. Threw it away so I can’t return it otherwise I would. Don’t buy.This light is so clutch! This has made fishing so much easier as I can see my fishing rod in the dark. Will buy again.I can't wait to try this surf fishing, pier and bridge. They both work great and seem to have a tight seal. I ended up buying the muli-colored. I read light color's are just as important as lure color's. Early April, I will find out if that is true.I asked for instructions and that solved my original problem. The lights seem sealed and secure and should work for deep dropping.Read some of the reviews and I strongly disagreed, if you look at the listing illustrations and fallow the instructions you shouldn’t have any issues.The counterclockwise is hard because it needs to be secured and watertight, remember 900’ deep you have big time pressures ( atmosphere ) to be exact.I will fallow up once used.So far I’m a happy angler ;-))))No instructions came with the product and it was hard to determine which direction the batteries went into the device as it wasn't labelled well. It was difficult to open and close which is good to not get water inside to wreck the device/light, but was almost impossible to turn to the on or off position. Better instructions and maybe a label thats coloured on the light to see would be helpful for future devices, for the on/off position. Care and maintenance would also be helpful, do you need to relubricate the ring etc? I wouldn't purchase them again, they are just not super user friendly for the cost of the item.Used it once for Sable fishing and stopped working by the time it got back to the surface. No water inside so that wasn't the issue.good product
