I use the keyboard mostly on a MacBook and a little with Windows. I completely wore down my first pair and reordered a second time, but in 2 colors - black and beige. So, since I had such good luck with the previous product, I decided to go with their new generation product, the Duo. So this was a great addition to my closet! Measurements are pretty accurate, and imo the size is just right. I haven?t experienced that at all maybe it varies but it?s definitely worth it for the price! Fortunately after a short breaking-in period, they are much more comfortable. No way to avoid that. I am quite happy! Its worked well for about 100 miles so far.
