“This strap is a signifigant upgrade from the stock Casio Duro bracelet. It feels very high-quality and durable. The strap is designed to sit nicely around the case so you almost certainly will have to fight to get it to fit.
My issue was spring bar related: the original bars and even the thinner bars included with the strap did not fit my Duro so I had to get an even thinner set. Once I did it locked in and it looks and feels great.
There's also plenty of room for adjustment on the strap size. My wrists are 8.5" and even I had to trim some rubber off.
I'm very satisfied with this purchase.”
