Review on 🚰 Smart WiFi Water Sensor 100dB Alarm: Tuya App Remote Monitoring, 5.9FT Leak Detection, Adjustable Ringtones by Billy Donalson

Nonsense! The batter was dead (and not charged) right out of the box. The instructions are confusing and in too small print for old eyes (even with reading glasses) to read without zooming in on the phone. When I first received this device, it turned out that it could not be charged. Was it plugged into USB for days and the blue light (indicating it was charging) never went out. There are water alerts when it's connected to USB power but not when it's unplugged, which tells me the battery isn't good (or nonexistent). I lost track of it and then remembered that I needed to connect it to my wifi and install the app on my phone. I couldn't get it to work. The instructions were somewhat cryptic and printed in microscopic text. Because I lost track of time when the return window expired, I couldn't get a refund :-( Revain was kind enough to give me a $5 promo (thanks!) so all I have to think about is my $17 tax " for not playing (and sending back) sooner.
