I'm an 83 year old guy who uses a walker (Rollator?) to get around. A couple of weeks ago, my rollator threw a rear wheel and I ended up with 9 or 10 parts that are usually packed around the axle. I needed to get rolling again so I did an internet search and found Monster Scooter Parts. They had the parts, they had the price and they performed. In a few days, I was up and rolling. You might say, I'm back to being a big wheel at my assisted living community.
