MIO Fuse Strap Size (Small/Med) There are scratches. Please check the condition in the images. The touch sensor was not responding, but it improved by "completely draining the battery and recharging it" as described in the web support. However, it may recur. Therefore, I am selling it as junk. The heart rate sensor works without any problems in terms of operation and accuracy. The battery drained about 20% during a 1-hour run. It will last longer if you only use the heart rate monitor without turning on activity mode. Be sure to look at photo 9 before operating. It is designed to not respond unless it is held horizontally to prevent malfunctions. [Shipping Method] Shipping via Yu-Packet Post mini. [Please Note] Returns are not accepted for junk items.
