Review on Wireless Keyboard Backlight Mechanical Breathing by Lawrence Feldman

I ordered this for my husband's remote work. Received and sent back the next day. The keyboard was ready to use immediately. Charged twice and never turned on. Either the internal battery is defective or I received a device that was previously returned for the same reason. Tried the bluetooth settings on the computer to confirm this. The mouse worked fine, but there was no way to turn off the light or stop all colors from cycling. The mouse worked perfectly on the first test. Test it the next morning and it's buggy at best. The product is a great idea in theory, but poorly implemented in terms of batteries. You cannot replace them if such a problem occurs. I prefer a wireless keyboard and mouse with removable batteries. I don't have time to wait 12 hours to charge my device. Also, the instructions are the worst I've ever seen. This was written by a bot. It might be English, but good luck trying to decipher it. I went ahead and ordered another wired backlit keyboard for my husband.
