These things definitely work but they don't last long in a marine environment. I might use them more than usual, but I need them to handle a lot of baits and a lot of times a night. I use 12v and AC adapters as the batteries don't last very long. I try to rinse with fresh water after each use, but eventually they get rusty and don't work. Now they get thrown out about every 3-4 months and I buy a new one. At least they aren't too expensive. I'm always looking for the best replacement.
