Pros: None

Cons: They don't work. Touch pad is very jerky and there are other issues too. (The one I bought last time, 3 months ago Left shift key was not working). It is completely useless.

Overall Review: NewEgg exchanged the 1st defective one free and sent another defective one. To replace the 2nd defective one, NewEgg wants shipping to be paid from my pocket which 8-9 buck 25% of the cost and there is no guaratee they will send good one either. Contacted Logitech. They are completely jerks. They claim they don't support, service or replace refurbished products even within the 90 day warranty. I really did not understand what is the use of the 90day warray. Infact, none of the Logitech refurbs don't work. I burned myself 3 times on NewEgg refurb Logitech items.
