Review on Waterproof Color Changing LED Underwater Lights With RF Remote - Battery Operated Submersible Lights For Pools, No Silicone Suction Cups Needed - LOFTEK by Fernando Hudson

Absolutely awful product since the new design. My mother bought me these as a birthday gift back in May. Long story short, I have a big pool.ten balls wasn't cutting it.I ordered another set of 10 end of July. So first complaint since getting the new set of 10 is that the batteries have already died before the original 10's did.they've drastically changed the battery compartment, it's a pain in the you know what to change , AND as I went to change them I learned these are clearly not water proof. Which brings us to the next and final complaint.we (a pool full of 6 people) were ALL getting little tingly shocks coming off these balls in the water once i threw them in.We took all 20 out of the pool and it went away.Don't waste your money. Especially if you're putting these into water as this is a MAJOR safety concern!
