I am very very impressed with the build quality and responsiveness of this unit. I had fully expected it to be a little on the shoddy side, and have it's share of quirks - due to it being an unfamiliar import brand, at a very reasonable price-point.
Instead I found build quality that I would put on par with most other top-tier Android tablets, and even bordering on Apple quality.
Screen is much better than expected, though a little on the unresponsive side at times (need a firm press, custom rom may mitigate this).
Screen viewing angle is a little weird, and require a litle a little towards or away from you for perfect image quality. Again may be more of a firmware issue than screen issue - but not poor enough to be a detractor from purchase.
Overall speed, storage and performance are exactly what I was looking for in an inexpensive android tablet. I am not disappointed in the least, and my seller CoolDroids was very helpful.
