I have yet to put this saw into wood. I did dismantle it a fair amount to inspect and found the design and build features to be top notch, it is precise and rugged, I suspect this will prove to be one extremely durable and dependable saw. I have heat cycled it a few times with no bar mounted, it pumps oil exceedingly well, has a good oil flow adjustment feature. The running saw impresses me as having loads of torque and the throttle response is zippy. I worked around the low and high needle limiters and adjusted for proper mixture at my site. The saw was initially a no start. I read about that on another comment somewhere. I got the ball rolling with a dribble of fuel direct into the carburetor throat. A few stumbling starts resulted after that priming, then came a solid throttle response. I have a lot of saws dating back to the 1970's and I restore vintage saws. I was moved to buy this saw because i wanted a fresh, new saw in the near 70cc class and more importantly the cs680 has the same tried and proven design features you will find on the most successful saws of the past, clear back into the 70's. No computer crap, a valuable manual oiling overide, simple straight forward design layout and so very easy to operate and work on. This saw is a case of success in the keep it simple concept.
I must also say that this Saw Suppliers outfit is the place to be for all your power saw needs, loads of supplies and saw stuff with timely shipping, fabulous customer service and prices that are as competitive as you'll find.

Good quality plug good price
I haven't used the saw yet, but the build quality appears excellent. Saw Suppliers was fantastic. They have the best prices and they even threw in a big bottle of Red Armor oil mix - very nice touch. The saw arrived very quickly and in great shape. Saw Suppliers will definitely be getting more of my business. Top notch folks!
