### ⭐⭐⭐⭐⭐ So well made and at a very affordable price for an ergonomic mouse.
*by P***V on 22 March 2026*

So well made, the right size and weight for most hands. I've used an ergonomic mouse before, it felt too bulky and slowed me down, not the case with this. It took just a couple of days to get used to it and after that it felt natural. Takes away the wrist stress the traditional flat mouse imparts. As soon as you unbox this, you can feel the love they put into this product. I'm really glad I took a chance on this, The material feel also feels so premium, it has sort of a leatherish feel - it is ofcourse plastic but has that sort of soft touch to it. And the blue black color also looks subtle and nice. I was not a 100% because of the fewer Indian reviews and a brand I was not familiar with.
