I just got a CM Storm Quickfire Rapid from Amazon. I really like how MX Blue switches feel, but there is one thing that really bugs me: there are a few keys that are not so clicky as others. When pressed, they provide a weak and soft click which is barely audible, unlike most others keys on the keyboard, which give a clear and precise click. I can barely feel the click. They kind of feel like brown switches, but I have pulled up the key caps and checked that they were indeed blue. At first I thought this counts as defective so I asked for a replacement from Amazon, but now I have got three replacements and they all have this problem. The only difference is the problem exists on different keys. Is this a normal thing for MX blue switches? Or I got three defective ones in a row?
