Allparts Toggle Switch Wrench

This seems like a great idea, but the execution does not seem the best. Like others have commented already, the teeth on the wrench seem like they'll wear out very quickly as the plastic is not very hard - especially on the finer, metric side. Due to this I also doubt one could loosen tighter nuts. Given the price, I was expecting it to be at least a bit more robust.
However, it does it's job, and there is not much competition...
