I wanted to love these shoes so much. It comes with three heights, which makes it super compatible with any type of trainer and bike. I was looking for a fast way to get shrink tubing since there really are no local brick and mortar hobby/electronics shops around anymore. I was just looking for something ASAP to protect her airpods, which she saved up for. Just set up a time and and frequency and this band will gently wake you up with a "nudge" (vibration) at the scheduled time. Their products are not following fads, they are innovative and quality for reasonable prices. I have to admit that the AT holds up very well against the far more expensive Shelter. Wouldn?t recommend Tsk, tsk Amazon. It even felt lighter.
