I sent them my Jura brew group for refurbishment. They received it on Monday afternoon according to my tracking, and I had it back in my possession that same Wednesday. 2 days later in perfect condition. Not sure about those other reviews but I can only speak to my experience. I couldn't be more pleased with the service I recieved.
After I recieved my part back I had a question about re-installation and emailed them. The service rep took the time to call me and walk me through my problem. I would not hesitate to use Jura Parts for any other needs. Thank you
