IOGEAR GBU521 Bluetooth 4.0 Micro Adapter USB
In terms of speed and performance, this adapter about as good as it gets with Bluetooth 4.0 support for some of the fastest wireless connectivity available and this model is also backwards compatible with older versions of Bluetooth, so it works with a wide range of devices at different speeds. The range on this model lets you work up to 30 feet away but you need to connect from longer distances you may consider a different adapter. However, the shorter distance means there’s less opportunity for unauthorized access to your system from other Bluetooth devices. Keep in mind this device also provides data encryption and user authentication so security won’t be an issue. This adapter works with versions of Windows from XP to Windows 10, and though it works with Apple devices like iPhones and iPads, it doesn’t support the Mac OS.
