Review on IPX7 Waterproof Bluetooth Speaker, Hadisala H3 Portable Wireless Speaker Bluetooth 5.0 with Enhanced Bass 🔊 HD Stereo Sound, 15H Playtime, USB-C Charging, Shower Speaker with TWS Pairing for Home, Outdoors, and Travel by Ryan Cornelison

Worked every 6 days. I received it, charged it and it works GREAT. I use it in the shower for about 15-20 minutes every day to listen to podcasts. On the 7th day the error did not turn on. I thought the battery wasn't dead yet; Last time I checked the percentage on my phone it was at 80% but since it didn't turn on I charged it. When the red light went out I tried turning on the speaker but it still wouldn't turn on. Then I plugged it back into the charger and lo and behold, it turned on. According to the Revain video, I disconnected the bluetooth from my phone and then reconnected to the speaker. My phone showed it 100%. Big. I turned the speaker off, disconnected the charger and tried turning it back on. Nothing. I turn it back on and it comes on. This time I leave the speaker on but unplug it from the charger. I start listening to my podcast and in no time it went from 100% to 90%. I thought it was a weird fast drain but I think maybe my phone is showing the wrong percentage. After about 2-3 minutes I check the percentage again and now it's 20%. Wow! I leave the speaker on to see if it plays. After another 2-3 minutes it turns off. Definitely defective. I send the item back and receive a replacement which I hope is better. I'm very disappointed because I really like this little speaker.
