The Ergohacks Verdict

Let’s get this out the way. This mouse screams high build quality. It’s got arguably the best sensor on the market and almost more importantly feels solid and strong.  It has ergonomic indentations that ensure a comfortable fit, a high DPI that cuts back on repetitive movement and sharply increases precision and it’s programmable buttons make it easy to personalize. Computer peripherals have steadily decreased in cost over the last year and although the RRP is around £50, it’s currently available on Amazon for £37.99.

The Castor is an excellent choice for anyone who does a lot of work with their mouse. It falls firmly in the simple-is-best camp and handles exquisitely well. I’m going to be sticking with it as my daily driver for a long time to come. Highly recommended.
