2 stars because the wheels technically work on packed sand, but they did not solve the main problem I bought them for.
I wanted to love these wheels, but after finally using them at the beach, I would not recommend them for the price.
The biggest issue is performance on soft sand. On packed sand, they worked fine, but so do most regular wagon wheels. On soft or loose beach sand, they did not perform noticeably better than our regular wagon wheels. The wagon still sank and was difficult to pull through the hot sand. I also did not think to stop and take pictures or videos at the beach, because I was focused on getting through the sand with a sinking wagon and just trying to get everything and everyone where we needed to go.
The second major issue is the width. Once the beach wheels are installed, the wagon becomes extremely wide and difficult to get through tighter spaces. We had trouble getting it into our room and had to unload the wagon in the hallway, remove the beach wheels, bring everything inside, and then repeat the process every time we left or came back. Once we got home, I was able to take a picture and a video showing that the wagon with the beach wheels installed does not fit through our door.
If the expectation is to swap back to the regular wheels whenever the beach wheels make the wagon too wide, that feels counterintuitive. I bought the beach wheels to make beach trips easier, not to change wheels back and forth while the wagon is loaded with all of our beach gear.
I ordered them from Veer earlier in the year but was not able to actually use them at the beach until recently. Unfortunately, by the time I found out they did not work well for us, they were already used and outside the return window.
For how large and expensive these wheels are, I do not think they are worth it. If you only plan to use them on packed sand or in wide open areas, they may be fine. But if you are buying them specifically for soft beach sand, I would think twice.
