I feel bad to say this,

but CM.Storm,

your CM Storm Quickfire TK really failed me hardly.

I dislike the non-standard + ugly layout of it.

It is so hard to compromise it for my gaming mouse due to the strange build of the numpad.

This mechanical keyboard really doesn't fit me.

brief review :
Pros -
Cool backlits.
Finely built.

Cons -
Cannot be modified.
Plasticky feel at the side.

However, I found another CM.Storm product that could replace the Quickfire TK which is the Quickfire Rapid TKL.

I haven't receive the parcel yet but it'll arrive in front of my doorstep around next week.

P.S.
CM Storm Quickfire TK had been sold within the usage of merely 2 days.
