BRIAN F. 
AustraliaBuilt Stihl Tough
Have not had a chance to take this out yet due to covid19, but I have started it and familiarized myself with the saw. Motor is not even bed in yet and only took 3 pulls on full choke to get it to kick, then 2 pulls to get it started. The decompression button makes starting this saw super easy. Everything feels very quality made and thankfully has the "made in Germany" sticker in the crank case. So far really pleased with my purchase.
