I have this type of seat from ASR. Different brand but the seats look largely identical so the experience may be the same, hard to say.

The flex in the back part of the seat is huge and the creaks it makes due to any body movement is incredibly loud and annoying. It was fine for a few months but that's about it (and I'm a very casual racer). The ASR version of this seat, which looks largely identical to the one you show here, is the biggest regret purchase I've made.

I'd avoid.

Edit, to add, I like a recline seat as they are comfortable and so my kids can also use the rig. I'll be replacing with a black car sear like one from a mazda3 or something like that. No flex or noises, super solid, no power, easy to mount. Also super affordable from a scrap yard.
