View answers- AutoIt's good in moderately demanding games like Cod; I have the 8/128 version.
Honestly, I don't have much to say. The Antutu score is far below what I got. The 366k is a good entry-level mid-range monitor with its 120Hz refresh rate and around 20 hours of battery life. In my case, I don't use it much because I study all day.
Pros- The battery
- Good performance (real Antutu 366k)
- Connectivity
Cons- Not bad for $120
