I have it two years,,,bang it fall on it...still works...they modified the harness, and it's even better than it was..
But...do what I did...call both companies, and try them both. Put it on yourself, and walk around...get up, down, cross your legs, etc. it's annoying if it triggers when you don't want it to.
When I go it, Bioness was 6,500 and Walkaide was 4500. But we all know. It's not the money. Its whatever helps more. I'll do whatever I need to tryto be better...went to Bulgaria from USA. Did Albany since twice.
