Im busy switching over to mx890.. uses same mrf-350 so thats easy ... but need to relearn ccp program now... some similarity to mx-editor but much more capable and complex especially the macro side... im still learning but many guides and training on utube...

850 battery drain bugged me and the whine it used to make when u turned the backlight on... other than that its pretty solid although ive been through many of them now they do fail rather easily - hopefully 890 lasts !
