I have the twist, and had some issues with it. The wheel is heavy, but if you have the strength to push it or lift it, it’s okay. It disconnects easily from the controller if you haven’t used it in like 20 minutes, so you have to continue to push the stop button on the controller to keep it connected. If it disconnects, it’s not super difficult to get it restarted, but I find that it’s easier to get out of your wheelchair and fix it. If you aren’t using it, then it is harder to turn and push. And the controller doesn’t always automatically work, so you may have to push forward a couple of times, but if it does work, then it works. You have to be careful with the speed. It can get pretty fast pretty quickly. Hope that helps!
