I had these for about 2 years now and they were starting to show some wear after the 1 1/2 year mark. I'm always on my computer so if you aren't on your computer everyday, these should last for a while but at some point you may have to replace them. Definitely agree with the other reviewer for options for capslock and tab. I would like to see an enter and backspace key as well.

Overall, I am very pleased with my purchase.

Love the keys and the grip on the keys are really awesome.
The one thing is I HATE that they don't include a capslock and a Tab key. I understand it's a 31 key set, but I think it's a bit ridiculous that I have every key on the left hand side of a keyboard, BUT leave out two keys which are caps lock and tab. The photo clearly shows this and it's 100% not mechanical keyboards fault. They're service is great, no complaints.
I have lots of ducky products and the quality is great, but I wish they just completed the keys on the left hand side.

In all honestly I just wish ducky made a full keyboard set and gave people the option to save money with the 31 key set, but provided everyone with the ability to get the full key set if they desire.

Overall great product

Very nice good grip for sweaty player's I would recommend to anyone that play's for hrs and sweats a lot this will help.
