Hi 👋, I have had both, but the Stihl version, I use the cut and brake on a twin solid brick wall, and I didn’t know, but it got Rebar inside it, It was a beginning, I’m a barn conversion , the barn was being used for storing grain, the whole I was trying to cut who is roughly 4 foot wide and 8 foot high, two of us all day or about six hours, time we got set up and cleaned up afterwards, The plunge saw Stihl was used twice to cut a window opening in a granite wall over in France in an old Mill, this was an excellent bit of kit. Didn’t quite manage to get through the hole in one cut had to go from both sides., whilst cleaning out a hole to put a tie been in the chain snapped, however, I did manage to get it repaired, I had both tools for approximately two years, but whilst I was away from site in France in 2019 December, I had both of them stolen, plus I don’t have all the kit, I lost approximately €15,000 of tools one was a big ride on lawnmower, Only thing I wish is the chainsaw was longer so you can go through anyone cut from One Direction , I’m now retired, living in France , Phil from the moulin France,

Just want to add some info. I went to rent the chainsaw from my local tool rental and I was steered away from it. I was recommended to use the cut and break instead. Was told that while the chainsaw is more efficient, a lot of people renting them have had issues with the chains and it can be expensive to replace. The cut and break is slower but more reliable. I'll be using it to expand existing window openings in my basement for egress. This is in Chicago.

I've had a bunch of bad reports about the 680. About fifty percent of the buyers are having a hard time keeping the saw running while cutting in the horizontal position. This is regardless of the maintenance done on the power head. The 695 is a much better saw, but way more expensive.
