Shop clues claimed 5 time quality check but I don’t think so, a single quality check.I have order 5 stage water purifier but not delivered on time, I try to return theproduct but huge time taken finally replaced the product after many calls during 5 months. Again, supplied product is damage & poor quality. It is continue water flow without any filter of water. Output nozzle is broken, cartage is old etc if you try to filter clean water output is more bad qualityeven not equal to DJB water supply. So that I don’t recommended to purchase.
