Micromax Canvas Express A99 - I had purchased this mobile 3 years ago and I find it most comfortable and optimized product of micromax at reasonable price. Till date, only one time I had faced a problem of hanging up and heating but it gets eliminated after a fresh setup from the micromax centre.
As far as the qualities of this product is concern, I found it very good and upto the standards in comparisons of other smartphones. The sound quality, design, look and pricing are appropriate as per the demand of market.
Internet accessibility via any company internet facilities, or through any WiFi system was well addressed and optimized in this device. It has a very different look as compare to other mobiles. Overall its a nice and comfortable device for me and hope those who are using or expected to purchase it, also find it good for them.
