After testing the MaySpare Universal Wheel Lock for several weeks, I can confidently say it's a decent anti-theft solution for smaller vehicles and trailers. The bright yellow-black color scheme definitely makes it highly visible - a great deterrent against casual thieves.

The lock feels sturdy in hand, with quality steel construction and a soft coating that protects your rims. Installation is a breeze - just adjust to your tire size (7-11 inches), slide it on, and push the lock cylinder. I've used it successfully on my motorcycle and golf cart without any fitment issues.

However, there are some limitations. The lock tends to stiffen up when left outside for extended periods, requiring regular lubrication. While it works perfectly on smaller tires, I struggled to fit it properly on my friend's full-size truck tires - the adjustment range just isn't wide enough for thick wheel rims.

The package includes three keys (a nice touch), and the lock mechanism itself seems secure enough to discourage all but the most determined thieves. It would take serious tools and time to remove this without the key. That said, at this price point, it's more of a visual deterrent than Fort Knox-level security.

If you need occasional protection for smaller vehicles or trailers, this is a cost-effective choice. Just be aware of its size limitations and maintenance needs if you plan to use it long-term outdoors.
