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

I bought the 10pk 3 inch balls for a 4-day/night pool-house party and they were amazing! They really set the ambiance and create a difference atmosphere. The balls themselves were durable and they practically functioned all night for 3 out of the 4 nights.All my guests were surprised and thrilled upon first seeing them.Unfortunately about 6 went bad due to water damage and upon inspection it seems that some of the threading were cracked, causing water to seep through to the battery. The products did not come this way so I assume it could be from over-tightening, heat from having the balls stay in the pool during the day, or just from general pool use as we did play with them quite alot.My recommendation would be to use some thread sealing tape before pool use if you intent to have excessive use, including play. Overall an amazing product and I will be using this brand frequently in the future.
