Dynamic MX070.12 Hand Held Variable Speed Mini Pro Mixer, Red

I was excited to try out my new MiniPro when it arrived. So I immersed the working end in water in a mixing vessel and started at a setting of "1" I got nothing but a buzz from the motor. Moving up to "2" on the speed dial got me more buzzing but no revolutions of the blade. Finally at "3" the blades started to turn albeit sluggishly. I went all the way up to "6" and was not impressed with the top speed and when I dialed back the unit stopped running below "3" I tried calling the manufacturer Dynamic at the N.A. HQ in Quebec. I was never able to speak with a live person and was disconnected 3 times at the voicemail prompt. Fortunately the folks at Kerekes were most helpful. I spoke with Carlos and he agreed the unit was defective and that I should return it to them. Susan graciously sent me the RMA materials and the unit is on its way back. With Dynamic's pretty long history of quality immersion mixers I'm pretty sure this was a one-off problem but on the other hand you might think that their QC would pick something like this up before it went into the box
