I have a CS Bolo that is about 6-7 years old. I reshaped the handle, which I thought was far too large to be useful, to a shape something along the lines of a Becker knife handle. I put a convex edge on it with a slack belt sander and 220 grit paper. It cuts well, and holds a pretty good edge. Definitely no complaints, but limbing on green wood, the Condor Bush Tool is better even though it is shorter.
After reading some positive things about the CS Kukri machete, I bought one this spring. During the first trial, limbing box elder trees, I not only twisted the blade, but part of the hard plastic handle broke off from the flex. Mind you, this was a branch less than 2" in diameter, it was standing dead wood, so it was dry, but box elder is a pretty soft wood. I actually plan on making a bushcraft style blade out of the portion of the blade that isn't bent.
