[This review was collected as part of a promotion.] The larger thumbstick makes it a little too easy to bump it with my thumb resting on the face buttons. But I really never notice this. The trackpad is a little bit smaller than the original Legion Go controller's. But that's not really noticeable either. What is noticeable is how comfortable this is for me. I have larger hands and the original Legion Go controllers were always digging into my palm and the plastic case I got for the system was my only real reprieve. I also bought these bulky 3D printed controller grips for those controllers. And I must say that the new controllers feel way more comfortable to me than the old controllers even with those controller grips on them.
Another big improvement is that the right shoulder button is now physically distinct from the M button on the side. It's still very easy to hit the M buttons on the side but I like that the shoulder button now has its own dedicated physical button. I haven't used this in FPS mode enough to say if it's any different from FPS mode from the original controller. But I did like that this came with a cover for the connecting port.
[This review was collected as part of a promotion.] Great controller. Works with the first gen and feels so much better. It is slightly taller which effects looks, but simply adding a shell case fills it in
[This review was collected as part of a promotion.] A real improvement over the previous versions. I'd recommend upgrading to this even if you have the original
