HP signed this keyboard is designed to resist liquid. to do this tray beneath the keys is provided with holes allowing the fluid flow in case of clumsiness. Otherwise it is about a traditional keyboard without programmable buttons, but pretty light. The legs under the keyboards that have a height adjustment. the keys are not as clear-called silent on some keyboard. Compatible Windows 8, I also used to writing this review from my Mac (limited use of this fact) It is the perfect addition to my laptop when I used the Dell office. I have put only 3 stars because apart from this resistance to liquids, this keyboard is classic. If you are clumsy so you have young children this keyboard is for you.
