I bought the device at the same time a Transcend 32GB Class 10 card.
However, these do not work with the Lenovo A7-40!
The device recognizes the card though, shortly afterwards, however, the Tab ejects a message stating that the card is not inserted.
Therefore my tip to all buyers:
* A card from SanDisk (tested, works perfectly) or
* A card from Samsung (tested, works perfectly) for this tablet purchase.
For Tablet:
* The unit is well made, although is made of plastic but feels dibasic.
* The weight I find quite high for such a small tablet.
* The touch screen works very reliable (no difference to the iPad for example.).
* The processor is fast enough, at least for normal applications / apps.
* The resolution is good, scaling the Appbeschriftung to fill the screen personally do not like me.
* Lenovo offers only after the purchase (current date May / 2015) on an update to Android 4.4.2 KitKat.
* The standard apps have expanded to include smaller apps like Norton Mobile (lite), the ebook reader txtr (lenovo edition), Evernote, AccuWeather, etc.
* The supplied bag is quite large for a tablet, made of synthetic leather, and a felt material which is however made of plastic.
* The bag is not really fit, it can be in your pocket but also store that also supplied headphones.
Conclusion:
* For the money you get offered a reliable tablet with good accessories.
