I bought the WiMiUS P60 and can personally attest that the specs are pure BS. It's disappointingly dim and has input lag. The corner correction is nice though. I replaced it with the Growview JQ818C and it's literally twice as bright and has 30 ms of input lag so it's great for gaming. No corner keystoning though.
