I ordered some replacement seals for my 9Barista - I've had my machine for 3 years now and use it everyday and despite what the guidelines say I find it useful to replace them after a while, I do notice a difference in the way the different parts tighten and how the machine itself behaves and delivers better, consistent quality shots. I was surprised at how fast the delivery was this time (last time it took about a week, this time it was delivered within two days!) I considered buying the seal somewhere else but I couldn't find that many shops that offered the same seals and they were considerably more pricey. This is the place to buy all your 9Barista gear and parts and I know it now!
