I thought I was mistaken. The ESM-9124 looks the same as the 2021 Gamesir T4 Pro except for the grip texture. And it not the bad thing, I have a Gamesir T4 Pro and the thing is a steal for 35$.
The EasySMX is very light at just 211 g compared to the 250 g Switch Pro controller. Customizing the buttons is easy but only if you can remember all the necessary button combinations as there is no UI to help.
