I bought Aquaguard Sensa in May 2008. Initially it worked well. However, after some time it started giving all type of problems. The Sensa mode stopped working. It automatically goes from Intell mode to UV mode, even though water in our area is quite hard.
And when we raised a complaint (# 0052943800) for that no one is ready to look at the issue. I have done 5 follow ups on that and every time same response that they will ensure that it will be taken care of today. But of no use. Today I got the worst ever excuse, "Sir our system is not working. I will ensure that your complaint is taken care of today".
I would suggest new buyers to never go for aqua guard product and specifically Sensa model. Probably users can go for Kent product. My friend is much more satisfied using that product. They also got some problem in the purifier but that was addressed on time.
