recieved mine a few days ago, typed on it all day yesterday. overall i'm pretty happy! they came sooner than expected, and feel a lot like DSA. the keycaps themselves feel high quality similar to the same material that's used for the cherry CRP rounds, which was the main selling point of these for me. there doesn't seem to be any crookedness in the stems either which is great news especially given how low quality a lot of uniform pbt profiles are. they also sound REALLY good, prolly the best sounding PBT keycaps that i have. the dyesub is pretty decent, tho there are a few keys that are slightly misaligned such as my X key, but not enough to notice at a glance and i'm more than happy to not complain too much. The biggest issue i've found is that the homing keys are slightly raised for some reason, either from the stem or the heigh of the keycaps themselves. I'm not really sure which is it since i'm too lazy to look into it further, but it doesn't affect the usage of it, just a little weird when you look at certain angles.
here's some pics i just took with powerhouse, i like this set much more on 40s than large tkls
