I ordered four of these handle covers (on a single order) and was a little disappointed with the product. First, you should know that these are not an equivalent product to those sold at a higher price point by some other vendors. These are much thinner, more flexible and give the handle a smaller profile than the other products, which was fine with me, but others may not like that. These essentially come straight off of the 3D printer so they feel a little unfinished, and the plastic stringing left by the printer is still present on the inside of the handle cover (at least on all four of mine). The cover slipped on to the handle of my Zuca cart easily, but I was also able to slip them off without a lot of resistance. The cover also turned on the handle when gripping it and twisting (like when picking up the cart by the handle or repositioning the cart at awkward angles). I cleaned the printer stringing out of handle cover and put it back on and the slipping was reduced, but then I added a little double-sided tape for insurance and they have settled in fine. The vendor initially responded to my message to troubleshoot by requesting pics; but then ghosted me on subsequent messages. To be fair, the vendor did approve a refund request after not responding to messages. Ultimately, I just made them work after missing the return window. All-in-all these are not bad handle covers, and they do their job of reducing the extreme temperatures of the metal handle on a Zuca cart, so definitely a plus; but they aren't the same quality or as much of a plug-and-play finished product as some of the other higher priced options that I've used from other vendors.
