I have purchased canvas turbo mini on last year December and from that day on I have not experienced any problem with the mobile.
It lags once in a week and no storage of apps problem as the apps can be moved to external storage. It is a very light piece and the look of white will be awesome I looks like aluminum back and it is 8mm thin.
This was the review after 10 months of usage and I am still using the phone even this review is been typed from the mouthshut app of my turbo mini.
