I have been having a Kent RO Grande and it worked well for 1 year and since then every month or the other there is a problem and I have to sell out 2-3K, I heard from others that they too are having a similar experience. I believe that it is not enough for Kent to market their products alone, they need to ensure that the product lasts for a long time. The worst part is after sales service which leaves a lot to be said.
I have finally decided to ditch this and go for a new one of another company.
