The H1 is a little confusing to me as it's supposed to offer a deeper sound signature than your standard JWK/Durock switch, but when I compare my Just Typing videos they sound very similar to me. They weren't modified the same with my Durock Linears having TX film while my H1s have Deskeys, but even then I expected more of a difference. I haven't taken a close look at the bottom and top housing molds as I typically don't care about that sort of thing so if there is supposed to be a difference I honestly can't tell. What I do know is the build materials are the same. The POM is stem, the top housing is polycarbonate, and the bottom housing is polyamide. Interestingly enough my Durock Linears are smoother than my H1 batch.
If I recieved the same batch of either switch I would enjoy my experience.
Almost half of the switches are sluggish on the downpress. I'm pretty sure it's a problem with this batch of H1's as I've bought from other vendors within the same month and they had the same problem.
These switches are extremely smooth and have a nice clack to their bottom out. In addition to this, they have hardly any spring ping(if any at all). They are definitely similar to MX Black retool/hyperglide switches. However, the MX blacks have a lot more scratch to them than the H1 switches. Paired with some light lubrication and switch films(and maybe a spring swap if 78g is too much for you) these switches make an excellent addition to any keyboard I put them in.
As nice as the good ones are, around 10 of the 90 switches I ordered had binding issues even after lubing the top housing and stem.
