Severely underrated

Really great switch, I really only use linears with UHMWPE stems so these caught my eye. Stock, they're useable, I personally wouldn't use them stock as the sound is rattly/plasticky compared to the nice full sound once lubed. Stock springs are great, Tecsee has really upped the game with these "exotic" springs coming stock with switches, as you can see now more and more switches are coming with dual stage. Wonderful experience, great sound and incredibly smooth push feel. These are my new go-to linear :)

smooth but bottom housing could be a little less brittle

switch overall is very smooth. the double spring makes it feel nice and poppy on the return stroke. my only issue is that the bottom peg that holds the switch in the plate is very soft and flimsy. I put a couple of them in a hotswap board to test the stock sound and feel, and when I tried to remove them out of the plate they wouldn't come out as cleanly as other switches (possibly because of the bottom housing material and the space for LEDs to shine through) Overall I do like the switch, but I would say if you are using them for a build to not remove them too aggressively, because they'll stay in your plate otherwise

You guys shipped them quickly thank you!! They are great, so freaking smooth and the colors look really cool too. The feel of the top housing is really smooth, and I lubbed my switches made them a whole lot better, but they are still decently smooth stock

Great feel and sound, quality can be questionable

I've had these switches for almost 2 years now and its an almost perfect sound when lubed (I used Krytox 205) and I've only had to reapply lube to a few keys once, my only complain with then is that there were a decent bit of imperfections when I first lubed them, very brittle housing, small bits coming off of the bottom housing causing them to be a paint to snap into my FR4 plate, and 2 or 3 had slightly too long of a stem causing them to have a gritty feel when bottoming out, overall these are great sounding switches for the price, but may require some more quality control when being made

great sound -- delicate housing

I've tried both the ciy switch puller, gateron switch puller V2 and a pair of tweezers and the only way I've found I could unmount the switch without destroying either the top or the bottom housing was by taking a pair of tweezers and delicately working all 4 sides until the switch pops out. I see a previous review noted that the bottom housing is brittle, which I agree with, but the top housing is also extremely flimsy as well. if you are new to the hobby, I strongly advise against picking up tecsee diamonds unless you're certain you won't need to unmount them for the foreseeable future.
