Especially for the price. XDA is hit or miss, I personally quite like uniform profiles. This set can be found elsewhere under different brands with slight differences though, and I'm not a fan of the arrow legends.
These key caps feel very good for the price. Lettering is mostly good with just a little bit of variation in size on the function keys. Some of those letters are slightly bigger than others but honestly something you have to look closely to notice. It doesn't' bother me, however, the space bars are terrible. There are other reviewers with the same problem. They are warped or too big which causes the key to clash with the keyboard case making an horrible sound. The solid green space bar did not worked no matter the angle and the weird one with the "put an end to plagiarism" worked a bit better if using it with the letters facing the opposite way. It doesn't fit 100% but the warpness affects less this way. Be ready in case you get the space bar lottery not on your favor.
