And even for a very specific brand, every model is very different. I got the 2 pack of these and it reduced my shoe collection from 2 large plastic totes to the 2 of these organizers under my bed. I?ve had these hooks for about a month now with no issues. in reality I think its just fine for the average person. The base of the mount is thick rubber which contours to the top of any helmet. Within about 20 minutes, I had a headache from how the set fit on and squeezed my head. Im uploading a picture of the inside seam to show its a 4 thread serged seam. These are everything I want in a sports headphone as I can use the hook of one side on my shirt collar if I need to be able to hear my surroundings better, plenty of battery, and sweatproof/waterproof. I had no problem with my license plates , but I have seen where some people have "zip tied" their license plates to the cargo basket so they are seen. It was easy to set up and it connects automatically every time.
