I have been riding Solowheels by Inventist as well as Inventists Hovertrax since last December. Hovertrax is truly only for indoor applications, which we use them for, due to their solid tires. Solowheel, the original, not the knockoffs, is as intuitive and easy to ride as Onewheel. It has an extremely far range, at least twice that as Onewheel and a bit easier to carry due to its shape and size. They maneuver just as easily and operate under very similar technology. With that said, after adding a couple of Onewheels to our stable this month, we can't stay off them. Skateboarding as a kid makes the Onewheel top of the charts for me. I received my Solowheel Xtreme, the 2nd gen the same week as my first Onewheel. Talk about having difficulty wiping the smile off my face. I do not use them for anything other than fun and do not rely on them for daily transport. I am however on them nearly every day just for fun and it's great family time as we all ride together. If you can afford an extra toy, in additional to a Onewheel, a Solowheel Xtreme is pretty darn nifty. Do not be fooled by cheap knockoffs. You definitely get what you pay for with Inventist much like Future Motion. Both superb quality.
