NOTE: i just recieved the keypad today.
I received the keypad today and upon first impression, im going to be honest. I thought it was bad. It took a while for it to start working once i plugged it in( like literally 5 minutes) i tried from the front usb ports, the back etc. I got it connected in the front usb ports located under my disk drive and it began to work fine.
Ok so, Now its all plugged in and ready to go, i set z+x to my default keys and began playing some osu! I was beginning to get worried because... i couldnt stream for anything on them, they felt hard to press (ironically) and just uncomfortable, i felt like i could single tap and stream 2x faster with my rubber dome.
I decided to remove the o-rings because i thought they were the reasons for the problems i was having and indeed they were. It began to feel much more comfortable to actually press the keys and play with them. They do indeed make much more noise now (the o ring greatly limited the noise it made) but i believe its better then not being able to play properly with them.
I have not completely gotten used to them but once i have and when im left alone in my home (Mother would get pissed at the wonderful noise of the clicking and clacking :p) i will fully test just how better or worst this keypad makes me. Ill be uploading a comparison video between my rubberdome and this Cherry MX (RED) keypad soon.
Also the tape at the bottom of the keypad peeled the paint off of my desk LOL, it still sticks but not as much. This isnt a problem for me because the way i position the keypad to play makes it so that it doesnt move but im not sure how it will affect other players.
Edit: Also the cable it came with was too short for me but good thing i had a longer cable that worked with it.
Another Edit: After 2 hours of usage, holy ball it feels great. 2fast4me
