Review on GMCELL 2-in-1 Bluetooth 5.0 Adapter with 3.5mm Aux Jack for TV, PC, Speaker, Headphones, Car, Home Stereo - Wireless Transmitter & Receiver for Streaming Audio by Todd Atherton

I have a hateful relationship with Bluetooth devices. So often people say "just plug it in" but that's not the case at all. Thankfully, this one keeps that promise. I was surprised to be honest. One funny feature, not in a good way, is that the brief written instructions are wrong, stating that the switch to toggle from transmit to receive goes in the opposite direction. It is said that RX means transmitter and TX means receiver. The good news is that TX actually stands for transmitter and it was very easy to connect the speakers. As the saying goes, don't always believe what you read. I have no idea about the battery life, but I'm not expecting much.
