Are there any alternatives?

The SteelSeries Prime Mini trims about 5mm off of the length of most competing mice, so there aren’t many direct alternatives.

　　If you don’t mind a little extra length, it squares off against the Corsair Sabre Pro Wireless, Logitech G Pro X Superlight, and Razer Viper Ultimate.

　　

How long will it last?

The Prestige optical magnetic switches are rated for 100 million clicks. Assuming 10,000 clicks a day, that comes out to just over 27 years before the mouse wears out. Basically, it will last until you decide it’s time to upgrade.

　　

Should you buy it?

No. The full-size Prime Wireless will be more comfortable for most people, and it’s a decent option at $130. The one exception is for those with small hands. There aren’t a lot of small, high-end gaming mice. The closest competitor is the Logitech G305 which is cheaper, but also heavier and with lower specs. Otherwise, pick up the full-size version.
