Review on 🔌 ASUS USB-BT400 USB Bluetooth Dongle Receiver - Compatible with Laptops and PCs, Plug and Play for Windows 10/8/7/XP. Supports Printers, Phones, Headsets, Speakers, Keyboards, and Controllers in Black. by Micha Dbrowski ᠌

- Microscopic size, normal price for its quality and features. - Easily and seamlessly installed the drivers from the disk on Win7 x64. - Supports work with Win8. - True indication of characteristics. Yes, it really holds 10 meters in open areas; I have a normal connection through the wall, provided that the adapter is located on the table in the USB hub. If you plug it into the USB input located at the back of the system unit, where, as a rule, there is a lot of metal and wires, then you can count on stable operation within 3-4 meters, but I recommend connecting it so that it is in direct line of sight devices, at least WITHOUT metal barriers. - Bluetooth 4.0 BLE (additional power saving), backward compatible with 2.1, 3.0 standards. I took this particular standard so that all currently known bluetooth profiles are supported, so there should be no problems with interaction with various devices. - Indication of work - barely noticeable blue diodes. They will not irritate with bright blinking throughout the room. With it, I connected a bluetooth keyboard, mouse and headset. Everything works great! The official warranty, which was provided in the store where I bought it, is 2 years.
