This product came with NO WAY to mount it inside my pool. No magnets, no suction cups. I'm still trying to figure it out. The backing isn't flat either, so attaching magnets is proving to be a challenge. I might end up having to just lay them at the bottom of the pool which was NOT my intent. The lights themselves are nice though and work great with the remote.UPDATE: after attaching some magnets with silicone and putting them in the pool, 2 of the 3 leaked and were destroyed.even closed TIGHT.
