I used these keycaps on my Corsair k70 keyboard and love them. Of course, the bottom row doesn't quite fit since Corsair doesn't have a standard bottom row. If you're considering buying them, just be aware that your keyboard needs a standard layout to be fully compatible. I like the feel of these keycaps compared to the standard keycaps that come with the keyboard. It's definitely more durable than the original keycaps and I really like how the keycaps let light through the sides. Overall I thought it was a very good buy for the price.
