I have this chain for 5 months in use and have sawed approx 4-5m³ firewood with her during the winter.
There were roughly split beech and oak logs, an average of about 20cm diameter / thickness.
The saw has since more than enough power - They went like butter.
She is pleasantly quiet and is good despite the perhaps somewhat wide engine casing in his hand. Heavy it is not, anyway.
The tool-free chain tensioner works very well. There will probably be a predecessor where it works somewhat cumbersome at mapped model with 2 adjusters there is no problem.
Loosen the black wheel the sword, tighten the chain with the Red, and fix it with the black again - easily.
For all the ignorant must be said:
A brand new chain is initially always lose power because the chain links stretch first.
Even a cold chain will stretch after the first cuts something, because the metal expands by the frictional heat ...
So first they will have to re-tension the chain for a time, which is normal!
I love this saw anyway fun - I can recommend it.
