I've used your gasket before (purchased from "wholelattelove"). I realized that buying directly from you, I can save a GREAT deal. I like much better than the original that was made by my machine manufacture.
Working nicely. the 8.5 mm is quite snug in my ECM synchronica; but only recently replaced. the gasket that came with my machine started to leak after 14 months of 3-4 pulls/day. so we will see how this one fares.
Works much better than oem. Much softer and holds a nice seal. Fit perfectly on profitec pro 700
