I have had a lot of trouble with this vendor around a touchscreen.
it's been 6 months trying to get them to send me one that is not broken. they have sent 2 screens so far wrapped only in styrofoam or bubble wrap. no hard cardboard box.
I had to pay to return each of the two screens to florida, then they don't respond until I initiate yet another service order.
now, they finally say that they will refund the paypal on the screen, but not the shipping, for which they want to give me a store credit.
and then, they shipped another screen, which after another customer service exchange, they want me to refuse, so it will get shipped back and they don't have to pay for another shipping charge.
this company is cheap, but the products are too, and it takes at least a month to arrive, and requires a signature on arrival (which means a long wait in line at our local post office.)
I finally paid the $80 for the TS/hub from MDD (which is supposed to come this week).
sometimes you get what you pay for.
