I am using this product since almost 8 months(earlier had Pure it classic 23 Ltrs). Must say this one sucks compare to earlier products.
Its only Auto fill works fine. Rest all the not user friendly.
It does not purify the water completely. Its very first chamber to remove dust and other particles is faulty and most of the time the you will find dust at the bottom chamber after just 15-20 days. Need to clear it regularly.
Also, the battery consumption is shocking high compare to old model. As its not enough, the autofill fuction fails at middle chamber anytime and water overflows.
Would not recommend anyone to buy as for same annual maintenance, you can get RO with permant and more reliable solution.
