I have 5 of them the oldest is 30 years old, the original which is blue. That one gets used just about every job. I’ve regular loaded about 500lbs+ on it when I used CDs. The next oldest (red) did have issues and had to be welded so no really heavy loads on that one. The R2, R12, R14 have been pretty dependable except for having put put air into the tires every once in a while. The R2 stays in my SUV and coming in handy for personal use even at the beach. You do have to be careful of the front wheels making sure it is pointing in the correct direction you are pushing. If it’s points 90 degree off it could snap, that happened once to me. I think they designed the front wheels years ago. All of my Rock & Rollers are that least 20 years old except the R2 which I brought to fit into my car. With these carts everything goes in in one trip. In NYC where we would have to wait up to 20+ mins for for an elevator at times that is so important. The Accessory that I got for it fairly recently, the bag for placing the stands in was very helpful.
