  1. Very helpful for deciding on which switch I prefer! 5 Star Review

    Posted by on 2nd May 2014

    Title pretty much says it all. I thought I wanted the CHERRY reds but now I'm set on the browns, and will probably be getting some blues for my IT job/developing. Thanks a ton CM!

  2. Figure out your preference before you buy a keyboard 5 Star Review

    Posted by on 1st May 2014

    I have been reading about the different kind of keyboard switches but how would I know which one to get? This sampler comes with 6 keys each with a different kind of switch. You can play around with it and figure out which one feels (and sounds) right to you.

  3. Really helps you choose a switch 5 Star Review

    Posted by on 30th Apr 2014

    Really great product, has the six most common switches to give you a feeling of how they feel and act. I'm moving from a rubber dome keyboard to a mechanical one, and this helped me out tremendously. Also, it's fun just to keep on your desk and mess around with. Don't even hesitate getting this, just get it now.

  4. TRULY A MUST! 5 Star Review

    Posted by on 30th Apr 2014

    This is a great tool for finding what switches will suit you best. While there are plenty of videos to describe how each switch type feels and sounds and can give you an idea of what you might want, actually feeling the difference is a MUST. I personally almost got browns without testing them and i found that blues are a perfect match for me. CoolerMaster even sent me a coupon for 15$ off if i ordered a keyboard from them basically covering the costs. An all around useful tool that everyone should have before deciding on your next keyboard purchase!

  5. Fun little hobby piece. 5 Star Review

    Posted by on 28th Apr 2014

    Though I use this mainly as a "paper weight", it is the greatest for feeling the 6 main Cherry Switch types. I am using it as a desk accessory, and conversation starter. Wanting to get more people interested in Mech keyboards.

  6. What I needed 5 Star Review

    Posted by on 25th Apr 2014

    I purchased this to help figure out which switch I wanted to get in my mechanical keyboard. The product is very solid comes exactly as it is described on the Cooler Master website. My only complaint is that the keys were a little hard to take off, but it isn't necessary thing to do since this is only a switch tester and not an actual keyboard. I would definitely recommend this product.

  7. Great Product 5 Star Review

    Posted by on 25th Apr 2014

    Perfect for getting a quick look at the different Cherry switches and for choosing the one that works best for you.

  8. Must buy 5 Star Review

    Posted by on 24th Apr 2014

    I was already pretty set on buying a CM keyboard but I wasn't sure which switches to get. This was a great help. There are some things that took away from it, though not enough to make it any less than 5 stars. First is that you can't exactly replicate the sensation of typing with just one key of the particular switch (this is no fault of CM, just an unfortunate limitation and it's still helpful). Second is that it took a long time to ship. A full week after I ordered it before it even left the facilities. The keyboard I ordered on the other hand came within two days :P But the $15 coupon blows these complaints out of the water.

  9. Answered my questions and a fun little toy. 5 Star Review

    Posted by on 23rd Apr 2014

    This seems to be the best option for checking out the various types of Cherry MX switches. each of the six really feels different and it's helpful in guiding me towards a mechanical keyboard. About the only thing that could make this better would be if there was some indication as to when the switch actually activated, like an LED that illuminated when a key is pressed or even making it work as a USB device You can easily tell with the tactile and clicky keys, but you can't tell how close to bottoming out you'd have to get with the red or black switch.

    My board included Blue, Brown, Red, Green, Clear, and Black.

    It's definitely a cute desktop toy after you're finished deciding about the switch you prefer. If you're considering at a CM-brand keyboard and don't know what switch you'd prefer, it's definitely worth it.

  10. Exactly what I was looking for 5 Star Review

    Posted by on 22nd Apr 2014

    I was planning on buying my first good mechanical keyboard and since I haven't had a feel for the different switch types I needed something to help me decide which switch I want. This did exactly that, I want the black switch (some typing, mostly gaming). I looked at some other testers and saw that they weren't mounted to anything or assembly was required. This tester is mounted solidly and the casing does not feel cheap. And you need a mounted tester, testing the switches without them being being mounted is almost pointless.
