Although I have not tried the Monokote Smart Cut trimmer myself, I would just say that ANY tool is awful if the user has not read the instructions and understtod them well. How many of you can honestly say you read the instructions COMPLETELY before starting to use the tools you are complaining about? Perhaps the manufacturers did not include detailed instructions (I know for a fact that to be true with my tap handle; I discovered later that you can force the bit deep into the "inner" chuck, as mentioned by JWN-RCU)
Now, how many of you have ever bought a tool you haven't used it yet?
More than 5 years and still haven't used it? Anyone?
