I give it one star because 0 star is not available. This is my 2nd Dell computer. This brand new Alienware m15 r3, which costs $2500, broke down right after 2 months. The tech support is horrible. Every time I try to call them, the waiting period is 20 min, not to mention that they schedule the wrong time/date, and the parts that need to be replaced take forever to ship. It's been 2 weeks since my computer was down, and I spent several hours making phone callas, and nothing has progressed at all! My first Dell workstation has the same motherboard issue, and they keep having this issue for years and obviously the product is not worth the price at all. The customer service is just a nightmare, and they dare to hang up on me after I spent 30 min waiting in the line! DO NOT BUY!!!
