If you are looking for a mouse and have 40 US dollars, I think you came to the right place. The Razer Viper Mini is a great mouse in this price range.
It has:
- 6 programmable buttons
- Maximum DPI: 8500
- Switch life cycle: 50 million
- Lightweight: 61 g
- Switch type: optical
- Approximate size: length 118.3 mm, width 61.4 mm, height 38.3 mm
I have been using this mouse for almost 2 years, and it's really great for gaming. In terms of performance, it has a great response time. I forgot to mention that it has RGB lighting, which you can control with Razer software in any way you want. You can choose any style you like. Personally, I love that feature. The build quality is also really great; it doesn't feel cheap at all.
Summary: If your budget is around 40 US dollars and you are looking for a gaming mouse that is lightweight, you should definitely go for it.
