Question: Are the metallic pieces made of stainless steel or aluminum?
Document: I gave the motor part with the whipping attachment to Goodwill and bought one with a stainless steel housing.
But these two I ordered at the same time? Lasted all of one month. To me, this model has officially become a &#34;piece of junk&#34; and will never buy again. Just ordered a stainless steel Cuisinart model and hope it is an improvement. Very disappointed that companies do not work hard to maintain their standards. Dud.
The mention of the whip being made of steel is obviously to trick buyers into thinking they are buying an appliance of quality.
I was simply trying to blend my potatoes, carrots, etc because I make my baby's food at home. Will only buy blender with a stainless steel shaft from now on. Also, the seal above the blade doesn't fully close off & allows food to get into the shaft, which I have tried letting it soak in water & soap but was unable to get it out. I imagine that eventually this food will start to rot over time.
this blender is great for what I need it for. however, I would complain that when using it often it heats up very quickly (motor inside) and gets hot to the touch. I also noticed that when washing the plastic blender water got trapped in the end of the blender. I have not been able to get the water out. it looks pretty gross. I would like this blender better if it were stainless steel rather than crappy plastic.
Two of the prongs on the immersion head broke off the second time I used this product. These plastic pieces were "blended" into my food. Buy an immersion blender with a metal head.
It arrived quicker than I expected. I had never used a hand blender before. I love it! Came in very handy. Some reviewers spoke of the plastic piece breaking. I would imagine if you were trying to break up bits or pieces that were sort of hard, it might be a problem. I only tried to break up some veggies that had cooked for a while, making them fairly soft. In short, I would recommend this hand blender!
It is EXCELLENT for making your own mayo or liquidating tomatoes for sauce. You can also get a nifty drink mixer attachment through the manufacturer. I have arthritis so the whisk attachment comes in very handy. The two speeds are also wonderful. It's lightweight (relatively), comes apart for easy storage, and easy to use. It may not be as sturdy as the big stainless steet professional "sticks", but it is a whole lot cheaper. My first one has lasted me years and is still going strong.
I think this started happening because I tapped it too hard on the rim of the glass to get the excess off. My daughter uses frozen fruit and ice and says she thinks hers did this because she hadn't cut the the pieces of fruit up and was using ice cubes instead of crushed ice. I started looking for a new blender but after researching it a bit, I decided that I really liked this blender and it fit my needs as well as any I read about in the price range I wanted.
I've used this blender almost every day for over seven years. Mostly used for making fruit protein smoothies, using frozen blueberries and strawberries which are pretty hard. I would occasionally blend ice and it handled it fine. Today, the attachment I use most finally failed while trying to blend something that was probably too hard for it (a hard protein bar broken into large pieces). Two plastic tines of the cup that surrounds the metal blades cracked off and began getting blended until I realized what had happened.
Answer: hmmm, I'm not sure quite honestly.  What are you trying to make?  There is not a lot of power to this so if you are trying to make things like frozen smoothies and stuff I would steer clear.  If you are just mixing powdered items with liquids and minor stuff then this will do the job just fine.
