Query: CHEAP PRODUCT...Bad and Painful Experience

Poor water taste..I hate even drinking water using this water filter.. Also water is dripping from filter outlet once closed..No manual was included. 2 pages of photocopied papers for installation (not a professional way)...Cheap product! Bad and painful experience. Returned to Amazon! BEWARE SHOPPERS, DO NOT BUY
