at $16.50 after discounts and everything, totally.
its very well built for the price, Bluetooth connection works perfectly fine and saves me a USB port.
it can toggle between BT and USB, so a second PC can just plug in the USB receiver without changing connection.
the buttons and scroll wheel bery solid, and perfect for those who like silent mouse. for me i dont like silent so its personal preference. the clicks are firm feedback, but obviously feels "muted" or "absorbed"
comes with 2 x AAA xiaomi batteries too lol
