TLDR: If you want heavier reds, a switch with an actual Thocc and no ping, the bassiest sound profile i've heard, a decent price, and you're lazy(they hotswap just fine), than yellow caps are for you. If you just want deep thoccs, these are just perfect. If you're gaming, these are just 5g heavier actuation reds, they feel just as smooth, if not smoother since weight tends to provide that illusion. If you have heavy fingers you might need a heavier switch, these are still LIGHT, I don't feel heaviness in a switch till ~55g. This is easily a 5 star switch if you're new to this, 3 star is you're experienced and want to do your own lubing which is why I give it a 4 star middle ground, its a great product. I already own 2 sets of these, first time buying from divinikey but they are American based which means better shipping costs.
They feel smooth, 50g actuation makes it just a little nicer than the the 45g force of the reds. Feels more cushioned(not mushy) if you have a light touch, just a tad harder to bottom out, though I didn't bottom out the reds very often either. There is no noticeable scratch to the keys in both feel and sound profile when you're typing normally, but if you intentionally type on the edge of your keycap you will feel a bit of it. Otherwise it is just smooth throughout. Obv when you're gaming with headphones feel is more important and these feel like any smooth linear, you forget about the switch and enjoy the game. Double taps and quick actuation are easy to do accurately.
These switches have no hollow, plastic sound, or metal ping. You dont feel any or it either, even when you bottom out. When you type with these they sound premium, with a deep heavy Thocc, compared to Novelkey Creams which sound a bit high pitch and cheap by comparison (but otherwise feel about the same). These give you a lot of the fun with mechanical keyboards without having to go through the work of taking apart 84 switches and lubing them, in fact these are probably not going to be the best switch if you want a project since they most likely wont benefit too much from using different lube. I didn't have much problem with leaking when I put these in, but I would recommend washing your hands before throwing on your caps. You might be able to build something better, but it'll come at a higher price point, and a significant time effort, not including trial and error with lubing properly.
These come in a nice case, and you do need a switch puller to remove them. That said they pop out way easier than they do when in a board, just a light force will pop them out. The cases themselves are actually kind of nice if you want to recycle them as some kind of switch art by plopping in different switches and making a 35key (or greater) tester.
