I returned mines too after 2 days of use. I visited a local McDonalds and both days after 20 minutes the web browser froze. Everything else would load up, but could not get a connection. This was at 2 different stores too. The market place had a lot of crap and Youtube videos were blury. The screen took a lot of effort and many cases the image on the screen darken or changed colors like if you press on an LCD non touch screen. It felt much like a childs or dogs toy, plastic, soft and squishie.
I got mines 3 days after I posted previously. I paid 99.74 for it and got 110.74 refund
