I give these babies five stars for being awesome. They snapped into the lugs on my watch like they were made to snap in the lugs. What I disliked about this product is that they didn't come on the watch that my brother bought me in the duty-free store in the Tokyo Airport. The makers of these spring bar pins need a more aggressive team of sales people winning more contracts so that noone has to buy a watch with sub-par spring bar pins ever again.
