I was having a hard time getting a new machine through insurance. I called this company and dealt with Linnea. She was able to get a machine to me without any hassle.

Eric gave me 5 star service. I did my research on machines before stopping by and I was nervous to try something new. Eric was kind, gracious and helpful every step of the way. Answered all of my questions, and even helped me with the set-up. Thank you so much! This could not have been any better!
