comment
" ...  It DOES fit my mi band 3 extra bands for anyone wondering. ... I already had a nice 3 band strap that functions more like watch straps with sizing holes. ... The 4 fits perfectly in that band.  ...  "

" ...  Beautiful colors and screens - took a minute to find my way around it versus the Mi 3 (which I loved and got lost during a camping expedition - didn't have the find device function active anywho).  ...  "
comment
" ...  That had a monochrome LED screen but was reliable and had great battery life. ... The BIP was good, the always on display was handy but n a dark room, hard to see but the backlight was good. ... The color transreflective screen didn't really display the colors well. ... The OLED color screen is just terrific. ... So, if you want a small, long life, really great display fitness tracker, you can't go wrong with the Mi Band 4  ...  "
comment
" ...  Screen resolution is awesome. ... One feature that would be great to add is the possibility to increase font size a bit as the messages display in a pretty small size.  ...  "
