I purchased this sheeter about 4 years ago and was very excited to save time with the built in docking accessory. Unfortunately, it was not a feature that was ready for release. I had constant issues with dough getting caught in it and the part itself squeaking loudly due to a bushing that had design problems. I called Somerset and after troubleshooting my dough recipe etc., they admitted it was a known issue but offered no thoughts on repair because they didn’t have any. That being said, this was 4 years ago, maybe they have gone through a redesign and figured it out. I’m not sure. Thankfully, the docking feature is removable and mine has been in a box since shortly after buying it. The sheeter itself is a great piece of machinery otherwise. Easy to clean and maintain. So I would caution against paying the extra money for the docking accessory without gurantees from Somerset.
