Be careful with Aquasure products guys. It works only for a little while, after that do not even think about any after sales service or spares.They seem to have a website where you can purchase spares but after you have made the payment even their own call center guys cannot find the orders. Their only response is that online orders are not visible on our system so we will call you back.
These days when orders are delivered within 2 days, these guys will sit on your order for a week, and then when you call they will try to scramble for the details of your order. And I am talking about such service in a city like Hyderabad, all the best to you if you live in a smaller town! BTW I purchased the original product from Croma and they have been really good in their service, only Aquaguard / aquasure is not worth the money.
