I bought this scooter because it was the cheapest model I could find from a manufacturer that I could reach on the phone if necessary. I am generally pleased with the scooter but have a few observations. . The fact that the manufacturer makes construction equipment shows. It is built like a tank. . It was extremely difficult to insert the two bolts used to attach the tiller because the holes didn't line up properly. I had to hit the bolts very hard with a hammer. . The seat is reasonably comfortable but very heavy . The scooter accelerates very quickly with a slight touch on the accelerator. This makes it difficult to use in tight spaces . One reason I bought this model was the armrests. But I ended not using them because of the weight and bulk they add. . I was concerned about my ability to insert the pin that attaches the seat because I have difficulty bending down but I found I could easily tip the scooter to the side a bit first which made it easy to do
