This is the third immersion blender I have owned. I use the appliance several times a day, and grew weary of wearing cheaper models out in a year or so. I trust this one will last a long time. 

Like other reviewers have noted, it is heavy, but I feel that's a sign of solid mechanics. It is surprisingly quiet and has little vibration in the hand, also a sign of high quality bearings. 

The one thing that irks me about this model is the illuminated light in the handle when it's plugged in. I use my blender so often that I like to leave it on a shelf ready to go, but I live off-grid in an RV and don't appreciate appliances that waste energy on lights when they're not in use. A minor complaint. I doubt it draws much power, but having to unplug the blender so I can sleep in total darkness is slightly annoying.
