I have had my unit pop off my helmet, down into the brush, out of a tree, more than once. I am not used to having things like cameras or the comm unit in a vulnerable position when I'm paying no attention, busting a hump up a tree. Now, with the Wraptor, I'm facing up more while ascending, and cutting things below me more. Easier on me and the comm.
We have challenges sometimes with one unit being the 'master' between two other units. The two others don't want to connect. Numerous times of trying to re-"pair"/ reconnect the units, but no dice. That was our last work day. Probably will be okay when we get the three together and re-"pair" them.
I"ll buy new ones, no problem, when needed. I will rig things now that I wouldn't have during the old shouting days. Lift and lower bigger pieces in tight places rather than piecing out.
