If you want the QRS Pro 2023 model, I have other auctions for the latest model with the new changes to it. Please let me know if yo want me to put up a listing. I have both the QRS 101.5 and the QRS Pro. Not 101.5 model. This is the Pro model that just came out. It is almost 1/3 the size of the 101.5 model and they have made it better. I have tried it with my injuries and pain and I can tell the difference each time I use it compared to the older model.

There are 4 new changes to the new model. IT IS NOT CALL THE 2023 QRS. There has been lots of control issues on pricing. Most people pay over 3000 or whatever the dealer thinks they can get out of the customer. Our price is 3000 which is map price. If you see it cheaper it is not the QRS pro model. If it is more, then that is extra you are paying the dealer. If we have advertising expenses we cannot sell this cheap. Those that come to our site pay more since we have google advertising costs.
