Thanks for the review! FKM rubber definitely has a nice, substantial thickness to it, but it’s built to be incredibly durable and comfortable. Glad you are enjoying the quality!
“Nice enough strap, but really isn’t worth the cost IMO. Nice and thick compared with their standard silicone, but the insides edges of the strap should have been rounded a little more for better comfort, they’re just too squared off. Even with the long strap, at a 7-1/2” wrist it feels ‘short’.”
