I have used Micromax Funbook Infinity for 1.5-2 years.But throughout the tenure, I was very frustrated with the performance of this tablet as it could not control multitasking and lagged a lot.I purchased it for around 5k.Few major problems in the tablet were:
1.Just 4gb internal storage
2.only 512 MB RAM
Eventually, I got rid of it and purchased a lenovo tab which turned out to be a much better buy as compared to this one,
