I had no previous experience with arcade sticks (a few times with a machine 15 years ago doesn't count). So i actually had no problem getting used to it. The square gate is very comfortable (i don't understand why some people don't like it). Anyways, if someone is thinking on buying it but doesn't have any previous experience with arcade sticks - don't worry u'll get used to it after one-two weeks.
By the way, the first unit i received was malfunctioning, when I would press X and O buttons together inclining the stick to the right, the character would continue moving in that direction. I had no problems exchanging it for the new one, and the new unit works perfectly.
I recommend the stick, buy it, you wont regret!
