Review on Eway Replacement Bands for Garmin Vivosmart HR - Soft Silicone Band (Teal, Small) by Rachel Ford

This strap fits the Vivosmart fairly well, although the button cutout on the side is so high you have to press hard for it to click. The screws were a bit difficult to assemble just because they are so small. The strap is stiffer than the original, so it's a bit difficult to put on and snap the buckle into the correct slot. The clasp is made of plastic. It looks metallic in the pictures.
