Review on 🔊 Wireless Bluetooth 5.0 Speaker, Floating Pool Speaker IP68 Waterproof with 8 Modes Color Changing Lights, HD Stereo Sound & Rich Bass, Hands-Free Portable Shower Speaker for Hot Tub, Bathtub, Outdoor by Prettyboy Capers

I have used this item 3 times in the month I have had it. Worked every time, turned on/off, displayed colors, played music. Have a good swim in my pool. The fourth time I tried to play it - it wouldn't turn on - none of the control knobs worked, the red and purple lights on the top panel were on and off and WATER was splashing into the speaker! This MUST be a WATERPROOF speaker! The speaker has never been submerged in my pool - just floated on the surface! This is NOT worth buying.
