4.0 out of 5 stars Mileage will vary according to keyboard & personal taste
Reviewed in the United Kingdom on 27 May 2018
There's really not much to say about these, they work just as well as any other o-rings. They're translucent, and I couldn't perceive any difference in my keyboard's back-lighting with or without them on. 200 is a good number which should suffice for a couple of keyboards, depending on how many keys they have, and whether or not you add o-rings to every key. The plastic box, whilst very rudimentary, is a better storage option than a plastic bag. For £5.99, there's certainly cheaper ones out there which do exactly the same job, but you are getting faster shipping (the cheap ones are often shipped from China and can take weeks to arrive) and the plastic box.

It's very easy to experiment with o-rings, as they can really easily be added or removed to key-caps, though the process is quite laborious for a large number of keys. They can probably last a lifetime, as o-rings probably never wear out, and they can be transferred on to new keyboards as you acquire them. After having used them for a week, I decided to revert back to not using them, but I'm glad that I tried them. I tried them on a keyboard with blue switches, so having o-rings evidently made little difference to the loudness of the keyboard, but they did alter the sound signature of the keystrokes by lowering the pitch of the sound. I would expect the attenuation of sound to be more pronounced on a keyboard with red switches, but I have yet to test this for myself. The primary reason for which I bought these is to mitigate the unpleasant feeling of bottoming out keys, but I was disappointed to find that the o-rings are relatively hard and make almost no perceptible difference on my keyboard. They also shorten the maximum travel distance, which I did not particularly like either. Overall, I found that o-rings made no significant improvements to my keyboard, but other people's experiences will invariably differ according to their personal tastes, keyboard model, and types of switches used. Given the inexpensive and long-lasting nature of the product, I'd recommend buying these, if anything just to experiment with, but don't get your hopes up too much!
