I ordered one of these & I think it's going to be a big plus in my life. It's made to use on hiking trails, beaches, snow. I've used mine on grassy areas, rutted streets. I really like it and thought I would just see if anyone else has used one. If you're unfamiliar with it, the website is gogrit.us. It's expensive but does have a 30-day trial so you can send it back. You use your arms to propel yourself.
