I bought a factory refurbished instrument in 2022, for my granddaughter, as she was going to use it for her High School marching band. I wasn't familiar with the brand but found a great review form "Better Sax" on YouTube and took a chance on it. She is now using it for her College Marching Band and is very satisfied with its performance. On two occasions, I have emailed Jean Paul Customer Service reps for a replacement part. They have always acknowledged my request, found the needed part, and got it to me quickly. We are verry happy with our purchase!
