I bought alpha and small engine keycaps for my ID75 ortho. The keycap feels good to the touch, and the typing sound feels good to my ears as well. However, there are very slight twist in most keycaps at the stem, causing rows to be slightly misaligned/zigzag. Addtionally, I received two "6 ^" keys, and no "9 (" key. I asked the customer support to send me the missing key, but due to the way ordering works for the Drop, I won't be receiving it. I was promised $10 in credit for keeping the keycaps, but I didn't receive any $10 credit.
