Review of Zenithink ZTPAD ZT280 C91 Android 4.0 Tablet PC

This is short review of the Zenithink C91 Android Tablet.  Zenithink are a relatively new Chinese company (founded 2007) producing Android based Tablet PC and TV products for the global market.  See zenithink.com for more information.

This is the first time I have ever used an Android device, so this is as much a review of the OS as it is the actual device.

First impressions

The box is simply labelled ZTPad with no mention of the company name which is a bit odd.  There are apparently a lot of ‘fake’ versions of this tablet being sold so you would think they would want to brand this at every opportunity?   Inside the box is a very small manual, a USB cable for connecting to your PC, a micro-USB to RJ45 cable for connecting to Ethernet, a US style power supply, and the C91 Tablet.

I had a quick flick through the manual but most of its contents were very basic and self explanatory anyhow.  Upon plugging the device in and switching on I’m greeted with the desktop containing a few basic applications.  Went straight into settings and configured the Wi-Fi with no problems at all.  I was then able to setup my Google account and go to the Google Play Store.  Installing applications is really simple.  So first impressions are very good, the device seems well built, and the screen response is good.  Tested the ubiquitous ‘Angry Birds’ game, and it works perfectly.

Usability

The settings, installation of applications, and general use of the device is mostly self explanatory and within an hour you feel very comfortable with the device.

Skype is preinstalled on this device, so I tested this with a friend doing a two-way video call.  This worked great, both the video and audio were clear.  The only thing I didn’t like about this version of Skype was that in IM mode the messages display in speech bubbles which takes up a lot of screen space and is pointless.  I’m not sure if there is a setting to change that?

Google Gmail works fine as you would expect, I have not tested other email accounts yet.  The built in web browser rendered all the sites I visited well including ours.

I tested playback of a few DIVX and XVID AVI videos which all worked fine from a 4 speed micro SD card.  Video was smooth and even the sound from the rear speakers was ok.

This device also has Adobe Flash installed, and this worked fine within the browser when viewing YouTube videos.  It did seem to have a problem with our virtual classroom though.  This seems to be a security issue in that it did not ask permission to take control of the webcam and therefore failed.  So this needs further investigation.

Conclusion

The build quality is good at least from the outside.
The screen is excellent, although very shiny & viewing angles are limited.
The front facing camera seems fairly low resolution but is fine for Skype.
The Wi-Fi reach seems weak, but this is probably sensible to save battery power.
Although the battery hasn’t been properly tested, the device seemed easily capable of lasting 5 hours or more during general Wi-Fi browsing etc.
It fully supports the Google Play store and applications can easily be installed and uninstalled.

So overall I would say for £126 which this cost from www.ebellking.com this is well worth the money.  The only question that remains is will it last, what is the internal build quality like, only time will tell on that front.

    Don't get it. I have had no end of problems with charging and how long it lasts. Never really got good use out of it

    Our Zenithink is still going strong after almost a year. The difference in price between these 'semi-unbranded' Chinese Androids and the top brands like Samsung is still large (2 or 3 times the price). Katie, I think the low specs you talk about can only be expected at this price level.

    DO NOT GET THIS TABLET! Honestly, can't think of one good thing to say about it. Full battery lasts maybe 2 hours with wifi, camera is low resolution and shifted, very weak wifi signal, very slow reaction most of the time, and button placement is awkward. You are better off saving a little more and getting the galaxy note.
