Thats exactly what all my comments are about. Personal trifles aside. They deliver, but if you get a bad unit, tough luck. Also i've bought units that were obviously used as they were full with dust. Its not that they are scam. Not at all, its that they have poor ethics. They could have at least cleaned it, but no.

If you get a good unit. Good for you, no problem. If you get bad unit, they will tell you they give you compensation, yet some people have been waiting for months/years for compensation and never got it.

Or what they get is a few months later a shitty worthless coupon.
