Karbonn K451+Sound Wave- not worthy to buy. Review on Karbonn K451+ Sound Wave

Hi guys. This is Navin and now I am going to share my experiences about Karbonn K451+ . As I purchased it about an year ago. And what I found while using it that it is the worst mobile which I have ever seen and used. The features on which I have purchased it were not meet up ever. As its sound is so noisy that it can harm your listening capacity. Hence the problem was started when I baught it. After buy I got to realize that its vibration was not working. Then I contacted to the seller and told him to change my handset. But he said it could be repair only instead of replacement. Then I called Karbonn customer care and told them about the problem and asked them for the replacement but they were not agreed on this. They were fixed on the repair and I had give my handset for a week. Then I decided to use it without vibration. And still I am using it without vibration. After 3 months approx its display got damaged. Then again I ran for the replacement but still the same problem exist. Then however I repaired it. Till then today I faced a low display. Right now it is not working properly. From some days I feel that its speaker is also not performing properly. Headphone was also damaged as I bought it. In total its a third quality product and not even worty to buy. Please do not dare to buy it. Go for other brands. Thanks for being kind to me. Please share and rate.
