I LOVE this knee rover. I am 65 years old and I had foot surgery and need to be off my foot for several weeks. The first few days I was so exhausted from trying to get to and from the bathroom on crutches or with a cane. My husband found this on Amazon. We spent time comparing this to other brands and read lots of reviews. THIS is the one to buy. I took it to my Drs visit and it rolls over door frames, curbs and the ramp safety strips with ease. The turn radius is great, it is easy to maneuver in my small house and fits through my narrow bathroom door. There is zero tipping and the padding on the knee platform is very thick and comfortable. The brake worked smoothly coming down the ramp at my Drs office. I felt very safe. It is easy to lift it and fit in the back of my small SUV (Hyundai Tucson) without needing to take it apart. The tires are big and there is even a shock absorber, which prevented any jarring resulting in pain to my foot. Now I can get around my home with ease. My husband put it together in 10 minutes. It even came with the tool needed to assemble it. The color is a beautiful sparkly blue and it has chrome wheels and a backpack that you can put on the front to be able to carry water, phone, wallet. I ordered this on a Saturday late morning, it said it would arrive on Tuesday. It arrived in ONE DAY. It was shipped within 2 hours of ordering it and it arrived the very next day on SUNDAY! This is worth every penny. Bonus - I asked my Dr if insurance will reimburse me since it is genuinely needed and he gave me a prescription, my insurance company will pay for it.
