VELOCIFIRE 9-Key Cherry MX Switch Tester, Switch Testing Tool for Mechanical Keyboards, with Clear Keycaps and O Rings

This thing has pretty much every gateron switch you should consider purchasing on it. If you're not sure what switch to buy in a prebuilt or use in your next custom build, this will let you know what you want. I highly recommend buying this if you are still in that space of wanting to try switches, especially given that this has switches that you don't normally see on boards except customs (Tealios, Zealios, Greens, for example.)Pros:1.) tons of switches. this thing has Tealios and Zealios, (usually $1 per when purchased in bulk!! expensive AF compared to other switches), butter on a budget gat yellows, blues and greens, etc. this has every kind of switch you could want to try that gateron sells.2.) These are *ACTUAL* switches. if you felt like it, you could slot these into any other keyboard you already own, given that it's either hot swap, or you have the time and tools to solder it in.Cons:1.) The keycaps are just clear, cheap ABS. They aren't special in any way, be that positive or negative. Custom builds or nice prebuilts generally come with thicker doubleshot ABS keycaps or dye sublimated PBT or doubleshot PBT keycaps. The nicer keycaps will make switches feel better, but you can at least get what the experience of using the switch is like from using the tester swtiches.2.) Fitment. The switches aren't super in place in the tester like they are in an actual keyboard. it's good enough for you to pretty aggressively type on them to try feeling what they feel like (the point of this product, lol), but they are not stiff enough for you to take around with you without the occasional one falling out. For me, it was only a handful of the switches that would fall out, with some being super locked in place and almost difficult to get out.

So, it serves its purpose just right, and it sure is a lot of fun just playing around with it. It even comes with a cutesy red keycap remover. Two minor problems though:A. No rings were includedB. The switches fall out super easily, so much so that requires some attention to pry the keycap off of the switch and it's downright impossible without taking it out of the (very nice) acrylic stand.Overall it provides a good sense of switch feeling, just wish rings were actually included and the stand was holding the switches in place.

These were nice for side by side comparisons of kailh switches. Ended up buying Kailh box whites for the satisfying click and general usability. I wfh so I type a lot.

Has truly helped me decide which switches I’m going to buy for my first build

Works fine as a switch tester for what I assume are the most popular switches. No o-rings even though product description and packaging they are included.
