I would never know. I just mailed them, described condition as very good, they revised the condition to "good". hence instead of 180, I get 150 (v.good gets 180). It was a refurbished that I bought at amazon, thats what probably got it to good from v.good if there was no display issue detected by them. Something is going on in the mail. I mail a v.good one to MaxBack, they mail me back defected one, I mail back amazon presumably one with display issue, they receive a perfect one and see no issue with it 
Now I just wait for May 15 before plunging in for a new tablet.
Thanks for getting the meter started up.

Well that's good, so what was the problem?
