My first and only buy has a serious quality factory issue: two keys not working, screw under a third one, and God knows what within the laptop. The shop I bought redirected me to Lenovo website for the exchange, three numbers later (two weren't working at all) I am waiting for a document from Lenovo then I can go back to the shop for the exchange. It might take 5 days or one month. I am a bit unhappy. At least the warranty is cheap (yeah?)
