Does it have thick keys?

Not sure what you mean by "Thick" but its a $35 keyboard, not the mechanical clicking you get from a real Mechanical keyboard but the lights are pretty bright it won't take much of a beating if you have gamer rage issues but otherwise its a pretty good keyboard for the price.

is Mechanical Keyboards?

I just received this Keyboard after ordering it on blackfriday and I can confirm that it is NOT Mechanical. It does seem like an otherwise acceptable keyboard.
