As mentioned in the previous review, the blade at the cutting end of the 66 bit notches very easily. In fact, it happened during the first 66 swabs I took with him. This appears to be the result of poor edge prep by the company that made the actual nozzle. I was able to fix this easily with a metal file and a blade sharpener. It's working great now and I don't expect any more problems with it as I've done over a dozen 66 shots and the edge isn't jagged. However, I believe that the tool should work right out of the box without the user having to make any changes or improvements unless they are made aware of the need before purchasing. If your work consists mostly of 110 hits with the occasional 66 hits and you don't mind fixing a bug in the 66-bit version, this tool is probably a good choice. If your work is mostly 66 strokes with around 110 strokes, you're probably better off avoiding this tool and buying something more reliable. Another problem is the hi/lo beat setting. It is unusually difficult to tune this instrument from lo to hi, although the transition from hi to lo is not that difficult. If you want to keep the same setting most of the time, this probably isn't a problem, but if you plan on changing Hi/Lo settings frequently, using this tool can be quite frustrating.
