These must be rare as rocking horse doo doo!
It says 10kg on the bottom of the backside. But that was when they were new and when there is plastic involved I would doubt they still hold that much.yes, I’d not seen these before. I’ll open one and try it on something modest. I wouldn’t attach one of these to a WX-1!
The box on the packaging picture looks like a mini.
I guess we sometimes have to manage our expectations in this hobby. These were probably designed to last 4-5 years not 40.That's better than my RT-2800 strap. It was made of vinyl pseudo-rubber, and the petrochemicals became extremely gooey. I had to throw it out.
