The last time I changed out my RO filters & membrane, the large seal on the membrane was defective. Within a day, it was obviously just the disgusting, salty tap water coming through. I had gotten the parts elsewhere before, but Isopure seemed to have good selection and prices, so I ordered here. Service and delivery were fast, but I think I may have paid extra for expedited shipping. At any rate, I got a good product at a good price.
