i have purchased this product works awesome. i bought it from a company called officetronics the first time who scammed me. sold me a refurbished one and told me it was new. officetronics is a scam. after being scammed by officetronics i went to tigerdirect and got it. works great no problems with the unit. i recommend it to anyone just watchout for a company called officetronics who sales products real cheap and passes them off as new when they are used and refurbished.
