The dodocool AC600 is among many USB wireless adapters available on the market. It is rated for 433Mbps at 5GHz and 150Mbps at 2.4GHz and is roughly the size of a quarter. Included with the adapter is product documentation and a driver disk.
I was able to install this adapter on a Windows 10 machine simply by plugging it into a USB port and letting Windows automatically install it. Once installed I did some speed tests across my network and found the device to be about 75% efficient as far as bandwidth goes. Given its size this is very good. Range with the device is average and actually performed better than other adapters I have used that were quite a bit larger.
Overall the dodocool AC600 is built well, simple to install and use, and comes with an 18 month warranty. Because of this, I have no problem recommending this device.
