My past experience with mobility scooters led me to believe that all seniors are flexible with knees that bend far enough to kick themselves in the butt. Sadly, I'm not included in that group. FOR SURE. When I saw the promotional photo, showing a man using your scooter with his legs almost straight, I assumed he was 4'9" tall, or there abouts. But, at 400 bucks it was worth the chance. Not only is your scooter comfortable and "non-cramped" it also has the advantage of a center beam rather than a wide platform to step over. Getting off and on is much easier than in the past. As with any product, there are some problems. No matter how I adjust it, the clamp tightening the frame to the seat stem will not close all the way. The thought of the seat suddenly dropping 4 or 5 inches while in use is concerning. I solved the problem by tightening a radiator hose clamp around the seat stem to prevent it from sliding any further into the frame. Also, this scooter is for paved surfaces and indoor floors only. Taking it over very mild "off road" terrain caused it all manner of distress. If I can't avoid those areas, I need more than a mobility scooter. The over-all assessment is completely positive. It is smooth, quiet, and fun to ride. Some of the cost saving devices are actually good things. For example, the bicycle-like bell which operates with a push of the thumb is a great feature. The "horn" in other scooters is actually the annoying back-up beep put to a different use. I've heard that the annoying beep isn't designed to tell others I'm backing up. Rather, it lets ME know I'm backing up. If I can't tell I'm going forwards or backwards, I have no business being on a mobility scooter in the first place. I've read a few negative reviews. If those things happen to me, I'll just buy another one. It will still amount to half the price I'd expect to pay elsewhere. Consider me a fan.
