Took some time to arrive but with free shipping I am satisfied.
I thought it might be uncomfortable to use but truth be told it's perfectly fine for me and I didn't even have to get used to it. It's expensive but it's got the modern features to back up the cost the battery life is also pretty good.
One comment I need to make is the size, it's smaller than a normal mouse. I have smaller hands and I like small mice so it works for me but if you don't it might not be for you.
