I have many rubber straps and clasps. But I didn't like this one.
My rubber straps from other companies, that I like a lot, are in the $30 price range (no clasp). Somehow this rubber strap doesn't feel good to the touch.
I have other clasps in this price range that feel higher quality, although they are a different design.
With this design, the 2 sides easily get a little misaligned. Easy enough to realign manually, but feels sloppy.
The opening mechanism is firm, which is good, but feels "cheap." This might just be the nature of this kind of design?
Overall this comes off more like a $30 item than a $60 item. Definitely not a premium feel.
There is a little bit of adjustability built into the clasp, about 2.5mm; requires a spring tool to adjust. So be aware that it's not a quick adjust, and even with a spring bar, you don't have a lot of flexibility and you don't have fine control.
The shipping was quick, even though this came from Asia to the United States. That was impressive.
I tried this a few times and gave up on it. I missed the return window (my fault).
I'm sorry to write a negative review because I know running a business is a challenge. But I have to be honest.
