Review on OMOTON Ultra-Slim Bluetooth Mouse for iPad and iPhone - Dual-Mode (BT 3.0 + BT 5.0), 3 Adjustable DPI - Compatible with iPad, Laptop, PC, Notebook, Mac Series and More (Silver) by Kim Adams

Unfortunately I think these reviews are wrong. Connecting via Bluetooth is anything but easy. Even after going through each step/instruction 20 times. With different devices, iPad, iPhone, HP and I even tried Android. Not once did the "green light" flash and nothing appeared on the Bluetooth devices to connect. It's incredibly light and the keys are very quiet. I'm also sure there is no cap on the sensor. I will most likely be returning the mouse.
