it's also very small, light and thin, pretty much impossible to find such compact watch since I don't want to carry bulky brick on my wrist (so no thanks expensive Garmin bricks with shorter battery life)
I'm now on my 2nd one, first I had brand new, it fell apart just before end of 2y warranty (basically the body inserted in frame without gluing, it felt outside, I could put it back and connect, just display colors were reversed but since it was in warranty I just used warranty to get money back, they improved gluing with newer versions), then went for OLED watch and gave up after maybe half year, gave new OLED watch which need to be charged at least twice a week to wife, it has unreadable AOD in sunlight (beause you need full brightness in sunlight or very least B&W AOD display instead other useless color combinations) and just bought second hand Bip for 20USD and I couldn't be happier, I'm thinking I could stock few of them into drawer in case something will happen to this one
plus for people with too much spare time Bip firmware is somewhat hackable with extended functionality
