Keycaps do feel a bit loose, and they are not your normal caps, and are too fragile, don't try to take them off or you're going to break them.

everything else is just perfect, I went with this over the 915 only for the reason that the rechargeable battery on the 915 is not AA or AAA interchangeable so I can't really fix it if the battery dies.

Very good keyboard. Mechanical and silent. The price is high but..... Every time I bought cheaper ones, I threw them away in a short period of time, like 8 months to 1 year. On the contrary, more expensive ones last for several years. I have another keyboard from a different brand of the same value for over 6 years of daily gaming. Usually, I change them to try others, and the older ones are passed on to children, wife, and friends. So, if you have the money because it is indeed quite expensive for our days, it's worth it. It also has Multimedia Keys that work with all my music and video programs, and extra buttons for macros
