I Purchased karbonn Titanium S5 through Flipkart because I wanted to have a big handset and also at a very affordable rate and it actually did not disappoint me.
The speed was ok with FB, Twitter and mails running and the battery backup was decent.
I like the aesthetics too of my white handset.
It was durable and after using it for about 11 months I gave it to my brother who is still using it .
Overall, A Value for Money Good Handset!
