I found this item on Amazon recently, & thought it might be of interest to anyone thinking about buying a mechanical keyboard with Cherry switches, but not knowing which colour key would suit them best. If you can't find a shop that has keyboards available to try out, this might be the next-best option. Of course what you do with it once you've chosen the type of key you prefer is your own choice! Maybe they can be found going cheap on Ebay?!
