2020 Echo Chainsaws 30.5 cc to 59.8 cc commercial grade comparison video

My name is Dustin with Echo Power Equipment Canada, and this is a video comparing the weights and performance of our main models offered in Canada. There are others that we sell, but these are some of our most common.
These saws range from the Echo CS310-14 all the way up to the CS620P.
These saws range from an MSRP of $299.95 up to $809.85 in Canadian dollars in Canada.
I wanted to show people the difference in performance, and weights of each saw so that it may help with their buying decision when looking for a new saw. Is it worth buying the $299.95 saw when I need to cut 3 cords of firewood? Or is it worth spending $809.95 to trim some small branches in the back yard? All Echo saws are classified as commercially rated, and come with a 1 year Commercial, or 5 Year consumer warranty here in Canada.
The cut times of each saw is as follows: These saws are mostly new out of the box, with no adjustments and they all had brand new factory spec chains. I was cutting dead and dry poplar, that had been felled a few weeks prior to this video, and the log is about 13-14" in diameter
CS310-14 43 seconds
CS3510-16 38 Seconds
CS4510-18 14 Seconds
CS490-18 16 Seconds
CS501P-18 13 Seconds
CS590-18 8 seconds
CS620P-18 7 Seconds
During the filming I did not know the exact times, but spoke on how each saw felt in the cut. I thought some were faster than the others, but going back on the footage, was incorrect.
