I got this brand because my neighbor has has a water purifier of the same brand and he was impressed with the service team. I went ahead and got this product last year and I am supposed to get free service of the purifier and after many texts and calls from aquaguard side for service no one came until I registered a complain. When the technician arrived instead of changing the filters he just took out the filters rinsed them and put them back.
I was really disappointed with this. Apart from the service the machine works quite well and I have not complaints regarding its functioning.
