Echo vs Stihl handheld blower (lateral torque)

this video (done by a Vancouver Echo - Shindaiwa dealer) shows, quite graphically, how the design of the Echo PB250 does not cause the fatiguing lateral twisting on the operator's wrist compared with other brands. Through a shrewd, simple design aspect, Echo was able to counter the gyroscopic effect that forces the operator to exert constant pressure to fight the machine twist, like on those other brands. contact me for the specifics as to how this was accomplished. ******PS In Canada, the PB250 is $20 less than their main competitor, with a 5 year consumer warranty, 300hr EPA/CARB clean air rating and lifetime warranty on the ignition module!!!!!!!********
