Buy it if you are on a strict budget and are willing to spend an extra $10 on aftermarket mouse skates (Corepads). Do not buy it if you have the budget for a Logitech G Pro Superlight or Razer Viper V3 Pro—the extra $120 buys you reliability, warranty, and a frustration-free experience. | Feature | ESYS Ultra | Logitech G
