I have used this product earlier good to use & easy & no as such problems faced. service was nicely given whenever required, I can say that it depends upon your usage how u make use of it, so then also products yearly life increases or decreases.
I was happy using this product. and recommended my friends too to take this product. You can take this product & enjoy the service & facilities. Specially its features are very cool which I liked the most. Now I am taking another products of voltas which are of greater capacity.
