We've already mentioned a number of PC gaming sale deals for Amazon Prime Day, and this is the second and final day of the sale event.

Save 53% off the MSRP of $39.99; looking at the price history for this mouse on Amazon, it is normally $29.99, so you save $11 on this sale. If you are looking for a small, lightweight gaming mouse, this is the mouse for you.

Compared to the regular Viper, Razer has shortened the length and grip width of the Viper Mini. As a result, Razer states that it is "recommended for gamers with small to medium hand sizes." This also played an important role in Razer making the mouse lighter.

It's not as lightweight as Cooler Master's MM720, which weighs just 49 grams, but it also doesn't have a lot of holes in the casing, if you don't like that kind of design aesthetic.

Just because it's small doesn't mean Razer skimped on features; the Viper Mini has an 8,500 DPI optical sensor, six programmable buttons, optical switches with infrared beams under the left and right main buttons, RGB lighting (body logo and underglow), and on-board memory for saving custom settings directly to the mouse; you can get all this for under $20.
