TTC Venus 45g Linear PCB Mount Switch

New to the keyboard game, but I think these are excellent switches! I would give a 4.5 if I could. Factory lube feels great, very, very, smooth switch. Hardly any stem wobble. Can't find any information on the materials used, but it doesn't really matter, they sound great, very solid and deep collisions. These are on a Keychron Q5 with tape, force break and a bunch of Rockwool stuffed in and it sounds really poppy/creamy in my opinion. Compared to the original Gateron Browns that came with the board, these are much less sharp in sound, poppy but not clacky. In the batch that I got, 2 had an issue where they felt like a silent switch, muted and mushy and a few had bent pins, but that's easily fixable. One thing that I noticed is that with my Cherry profile caps, the home row, being the shortest, had some issues with interference. The inner keycap would touch the rounded side part of the top of the switch. When you press down, it would sound and feel creaky. I took a nail file to the edges on each side of each switch and the problem went away, but something to be aware of. Outside of that though, really excellent switch. Would recommend.
