Strong believer try before you buy!
I don’t think I have missed your point; the noise is the factor with this type of equipment nothing else, but can also be equalled to some porty’s and yes arrogantly of me not a lot of difference to a road drill working but less time, believe there is a cut off time for noise?
Nether for or against a TM it’s a tool at the end of the day a good one at that!
