Review on 📱 TUNAI Button Bluetooth Remote Control Kit: IPX7 Waterproof Phone Controller for Car, Bike, and Motorbike Steering Wheel - Stereo, Audio, Siri & Camera Control for iPhone and Android by Charles Fowler

I bought this TUNAI Bluetooth Media Remote button to control my Windows 10 PC. I have several similar bluetooth remotes that compete with TUNIAI and work with my PC. The Tunai button is a perfect match for the PC. HOWEVER, after connecting, Windows reports "Driver Error" and the device is unusable. Low marks for "ease of use" - initial pairing was easy, but unpairing and re-pairing was a hassle, especially since manuals for this device are hard to come by. No paper upon delivery, not even a link; Googling found old Tunai manuals, diagrams that didn't look like what I got (e.g. my device doesn't have an iPhone/Android switch), and the instructions didn't work. I finally found the right guide on FunkeyIt's "Reviews" page.
