This keyboard which was purchased for 21$ on sale was well worth the money. I'm able to use any where in my room with zero noticeable lag. The left mouse button located in the top left of the keyboard makes dragging and dropping things very easy which is something most wireless touchpad keyboards have trouble with. This keyboard is definitely worth the full price of 40$. for 20$ I'm laughing.

This laptop crashed less than 2 weeks after I purchased it as a Christmas gift for myself. Not dropped or otherwise mishandled. Registered my warranty 3 TIMES with customer service (registration was always "lost" even though I had a reference number for each call). Toshiba required that I spend hours on the phone with tech support after each registration to attempt a cyber repair. Always told a return mailer (at my own expense) was on it's way. STILL WAITING! DO NOT PURCHASE!!!!!!
