Love it. Wish they made a Linux driver. It works fine but horizontal scrolling is nicer on Windows with their driver and utility app. I’ve spoke with customer support and they said not expect full Linux support any time soon but that it could come in a few years. I had some RSI from mousing and this helped. Easy to use left or right hand and keeps your hands near the keyboard home row. I keep one at work and one at home but both I got used for about ~$60.
