## Customer Reviews

### ⭐⭐⭐⭐⭐ Great when travelling with Sim card for data
*by B***S on 29 January 2019*

Good battery life. I get about 6 hours viewing video stored on external usb or logged online. Very acceptable picture and sound quality. The sim card is great for data when wifi isn't available. I use payg from "3". Really useful when travelling in Europe and avoids using unsecured free wifi.

### ⭐ Not goid

*by A***R on 11 February 2018*

Reasonable tablet for the price. Couple of negatives are charging cable awkward to insert and wireless is weak - get a speed about one quarter of that I get on my iPhone. This is not an issue if your wireless download speed is fast in your location but if you struggle to get a really good download load speed generally then this may not be the tablet for you.
