I recently ordered my 9th Barton strap - a 22 mm Silicone Elite. I have 2 other Silicone Elite straps, and I really like the keeper with the tab in it to prevent its moving during wear.

This strap, ordered from Amazon, was missing the keeper with the tab, so I wrote to Barton customer service. They responded the next day and said they'd send more keepers. They arrived today.

I like Barton straps and will continue to buy them with confidence.
