I purchased 2 vinyl cutter from them and one out the box had a blank screen and the other just sits and hums with no movement, I contacted Vevor sent video and pitchers and they responded we will send you a mother board and you can replace it. I an not an electrician nor an electronics technician plus it voids the warranty if I open up the device. Don't believe the hassle free return and refund that is all a lie stay away from this company if i could reach the world I would tell them stay away there all lies and no customer service. They just want your money. I they give the same lam generic email responce to everything.
