Didn't really know what to expect but like the look of a waffle strap so tried it out. It looks great on my Citizen Eco-Drive Diver (pictured), much better than the original strap, and I am currently wearing it on a Seiko Marine Master 200 (which came with a very nice silicone strap, but I actually like this one better). From looking at photos, this appears to be the same strap, or likely made by the same company, that Uncle Seiko uses and that strap is rated very highly.
As a side note, i made a mistake ordering one of the other straps (wrong width) in this order and reported it immediately, but the message wasn't seen before shipment. When they did see the message, BluShark got back to me and sent the correct size for free - amazing customer service! I had heard they were great from others and am happy to confirm that assessment, would definitely purchase from BluShark again :-)
