Not OP, but the buttons are a bit mushy, the shell a bit creaky and, worst of all, the the Steam and Quick Access buttons feel terrible. It's all much more apparent when I pick up my Switch Lite, which itself isn't something I'd consider high build quality. That said, I'm ok with the compromises considering the price point.
Am OP, and yeah this is pretty much it. For me it's the fact that it's a huge chunk of not-great-quality plastic, when all my other devices are aluminium or better plastic. I'm lucky to have had no issues with the inputs, but they are known for having problems.
I'm also absolutely fine with these trade-offs for the price point, and in fact if pushed, I'd probably rather have a £400 device like this compared to a £500+ device with the same spec made of aluminium with slightly better inputs.
Genuinely curious, what do you consider low build quality on them?
