These lights work well. One did have battery corrosion even though we took them out every night (this is a must! The lights can’t stay submerged overnight) The lights were fun colors and did not attract any additional night bugs.Other then they work great they only come with 1 remote and they float. Will not purchase again unless seller sells units with with separate remotes.Used submerged in pond for 2 weeks. Light went out. Removed and changed batteries...still wouldn't work. Allowed it to dry and re-inserted batteries. Used to mark a path on dry land. Then they stopped coming on altogether! Don't waste your money!Looks super niceDidn't work with my tiled bathroom wall, may need to purchase my own suction cups, and they aren't the brightest, HOWEVER, they would work great in a pool. Due to the cool flashing colors I decided to repurpose them and laid then flat in my bedroom. Also, I noticed they work well with glass. This company has very good customer service!! Very responsive.These little remote control lights offer perfect ambiance to my garden.I let these little gems float in the fountain in our courtyard and change the colors for different occasions. It adds a fun touch to the other landscape lights and I really enjoy them. I wish the remote worked better from a short distance but it only works when it’s very close to the lights.Only 2 remotes for 4 lights- returned
