this product having main problem of hanging . it hang continue. and also have the button problem some of it,s button not working properly. and display showing garbage. the sound quality is really good than nokia mobile. i suggest to flipkart that you should increase product price but give good product.
sound quality: 8.5/10 (pretty decent, better than nokia cellphones) looks: 4/5 (like a pendrive with few extra buttons, nice convenient lock slider) data transfer: 1mbps minimum (pc to pendrive) 17mbps minimum (pendrive to pc)
final conclusion: simple and decent. fm reception ability is very good. im just confused about what to do if it hangs... cuz its unable to shut down after that. might need to drain the battery off..
