I am using this aqua fresh grand RO since Sept. 2016 and I found this is the best RO in the market, because there are so many brands in the market but aqua fresh is UV technology based not only showing sticker but its real works for UV. It is very ease to use molding on wall the looks of machine and style design of the RO is beautiful, body metal and motor of the RO machine durability is very good, this RO can be convert 2000 TDS hard water into soft and sweet drinkable water, there is 4 services are free with by the company with carbon filter change and support of company is so nice, if you are planing purchase RO I recommended this.
