I bought lava iris x1 grand dis Feb 2015, it had many new features for very less price. features such as circle phone cover attracted many, this feature was only in LG mobile which was around 40INR but the lava iris x1 grand was just 6.5INR.
The draw back of this mobile is once if you stop using the circle cover given for a while then the phone is getting hanged again when the cover is used and initially the phone was good and very fast but as time goes it became very slow its not even 9 month since I bought.
On the other hand my friend bought 40INR LG mobile which has same feature but working very fine even after a year and a half so by this I can understand always brand makes more sense than cost.
