The user experience is sluggish and during our time with the tablet we experienced a number of system crashes. Sometimes, when running an application or browsing a website that was particularly image-heavy, the device would seize up and throw us back to the main menu.
Videos run well on the Ubislate, however. They don't look particularly nice, but it terms of frame-rate there's not much to complain about. We ran videos off of the SD card and through the YouTube application (which we downloaded from the Google Play Store) with relative ease.
Whereas video playback is fairly lag-free, internet browsing is a different story. By default, the tablet comes with Ubislate's own browser, UbiWeb. It was a truly hideous experience having to navigate the web using UbiWeb, so we quickly ditched it and installed Google Chrome.
Running on Google Chrome, the Ubislate 7Ci is still a slow experience. One possible fix can be made by telling the browser to show mobile-friendly versions of the sites you visit the most.
We ended up uninstalling around 20 different applications that shipped with the Ubislate that we simply didn't need. As the tablet is primarily used for educational purposes in India, there's a load of apps aimed at the little ones piled onto the 7Ci's memory.
In general the Ubislate 7Ci offers a very slow user experience, but if you're not asking much of the tablet, it's just about usable.
