To be perfectly honest be very careful about buying off name Chinese branded Tablets, they have got better in terms of quality but still can be iffy.
1. Plastic front and back easy to scratch and on the bulky side.
2. Low end CPU/GPUS or even versions that are very old
3. Screen quality.. The IPS versions are decent but a swath of them use very poor quality knockoffs that are just horrible.
4. Internal RAM controllers are known to fail... I don't need to get into what kind of problems that can cause.
5. Battery Life... usually very Dismal..and battery quality is bad they don't last to long.... @%50 Brightness you might get 4-5hours on use
5. Speak quality or Lack of... Low volume, one speaker with Meh sound are common complaints.
6. Forget about customer service or getting it repaired they are poor in this department.
It really depends on how much you use it and what size you are happy with, for me a 8 inch was a perfect balance of Screen size, weight and Bulk. It fits in my coat pocket or Backpack and offers enough Charge to get me through the week.
