The original band that comes with TomTom Spark 2 is poorly designed and starts tearing where the strap meets the hard plastic after a months of use. TomTom replaced it for me free twice while under warranty. When the 3rd one wore out, I refused to pay $30 for a 4th one (knowing full-well that it wouldn't last). I've had this band since Christmas (7 months) and it's still going strong with no signs of wear. Sure, it has it's annoying pitfalls (excess strap slips out of the retaining ring constantly and the metal will cut into your wrist if it's too tight), but I can deal with them! Tip - when running, slide the retaining ring close to the metal clasp, fold the excess band in half and slip it underneath and it will stay!Vendor - should you ever design to update the design, add a small tab to the underside of the retaining loop that will fit into one of the holes in the band to secure the strap.
