I am a civil engineer and home renovator not associated with bosch or Bunnings. I don't have any other 12v bosch tools, I use either Makita or dewalt mostly.
I bought this saw for $199 from Bunnings a few months ago, used it for tight timber cut outs, plaster board outlet holes and pvc plumbing. It is fast and easy to use, no vibration, certainly the best method for cutting off in the wall. Beats a renovator tool for plunge cuts hands down. Will cut a 100mm radius if need be in melamine. New blades are expensive at $46

This is the perfect lightweight but powerful handheld saw for smaller jobs, I use it as a pruning saw, it does not vibrate in your hands and is very comfortable to hold. Comes in a sturdy carrycase. May seem expensive but it is worth it.
