These guys are very very helpful.My condition, Stiff Person Syndrome, had taken a bad direction and I need a walker for a conference I was going to. In less then a week they found a newly designed walker checked out the design and performance before ordering it, in order to make sure it would be good for me. Then they jumped through hoops so that I could get it before I left (I had thoughts about no going because of my stability issues).*Ive never written a review before, but needed to for them.
