I don't mark many ribbon cables but carry two TLS2200's in my truck, use almost daily.
Pretty broad range of applications, I use mine mostly for wire marking, some component marking and panel lableing.
LabelMark software makes making a bunch of labels handy, and you can save files for reuse.
At least for me, Brady's service has been good, fast turn around on repairs and upgrades.
Large varity of labels available.
Doesn't like dirt and rough handleing. In my former company we had a couple in the toolroom, always had problems with them, when we issued them to individuals we had fewer problems.
Labels are pricey, not the cheapest solution out there.
Battery life sucks, both of mine have AC adaptors, a must have if you do more than 100 labels a day in my experience.
We had a couple of tough marking problems, called Brady tech support, told them what we were trying to mark, the printed some samples and sent them out for us to try. Some worked and some didn't but the only investment was a little time, and in general they used to be pretty helpful.
The self laminating markers have held up pretty well for us, after several years most sites are still readable and in pretty good shape. Some calibration and ID lables exposed to the sun have faded, but in general compared to other brands we've had pretty good luck.
Hope that helps.
