I have used this Quattro for 3 outings so far, and it holds up very well. It is stable when pushing the cart, and I especially like the quick-release handle -- good for a quick adjustment when walking up/down steep portions of the course. Also, I didn't realize it came with the bottle holder, so that was a nice surprise when I opened the box. Assembly was super easy. Folding/unfolding super easy as well. It is a very compact and light model -- which ended up being the 2 items that drove me to choose the Quattro after much research. Well built and appears it should last for many more years to come.
