Then buy the Gorillas. As I said in my post, the Gorillas are good quality for the price point. Certainly better than the factory 2-piece nuts that like to come apart. If you go with the Gorillas just be careful when installing/removing to not chip the coating. If the coating doesn't chip, they will likely never rust on you. If it does, you may want to cover it as they tend to rust when the coating chips. Most reviews I have seen are happy with them (because theirs did not chip). Occasionally you run into someone who had a nut rust on them (because they chipped).
The reviews on amazon are fairly representative of what I have seen on forums/heard from users of Gorilla nuts. You will find a lot of high reviews because they held up. You will find a few (certainly fewer than the high reviews) where the nuts rusted on them. Sometimes within the first few weeks of ownership.
