Review on Outmate Stainless Carabiner Seawater Keychain by Brent Peterson

I bought these because I used them outdoors and wanted the best rust protection available and felt they should work. I hang our bird feeders on it and can easily release the carabiner. I haven't had them long enough to see if the spring release is rusting or not. I'm assuming the spring is also stainless steel, but I'm not sure if it will continue to run as smoothly as it does now, time will tell. I felt they would get the job done for years without any issues like rusting and the price is very good for a 316 stainless steel material. I also needed the length, that is why the heavier ones are longer than smaller ones. Also, they were super packed in a display case to hang on the wall instead of tossing them all together in a bag. That's what the manufacturer tells me. is proud of its product and should sell well in the store. Many Thanks
