Question: Has anyone found a safe technique to clean the top of the hand blade?  It is quite sharp and the blade's top does not seem to clean thoroughly.  Tx!
Document: The sharp blade on the chopper is extremely sharp; on the high speed, nuts are pulverized quickly.The whisk is particularly useful when combining hot liquids and beaten eggs. Because you need only one hand to operate the "smart stick", you can control the pour of hot liquid into the eggs much better than attempting to mix the two by hand or when using a regular hand mixer. I found I was less likely to have coagulated egg pieces in sauces, etc.
I think this is such a handy product to have. I wish I had found it sooner and would recommend it to anyone.
I also effectively blended a cream of celery soup. The only problem I've had so far is with the top part of the whisk attachment, which was not as dishwasher safe as I would have liked--it did fill up with water when I washed it in the dishwasher, and I can't get the water out.
What? Its a blender. of course it has sharp edges. No. Not on the blade. On the 'foot' of the thing.Look at the photo closely. See the nice shiny metal blender end of the thing? Yeah. That's real stainless steel, no cheap electoplated plastic here. It really is a marvel of metal forming technology. The downside?
I've been quite pleased with this blender. Nice looking, and works exactly as expected.I probably should have gotten the version without all the attachments because I don't really use them, but I'm not unhappy with them by any stretch.The only reason this got 4 stars instead of 5 is that the blade is surprisingly fragile, and I've already bent it a little by trying to blend some hard cocoa butter in a fluid.
This is the best gadget I have EVER bought! I like it even better than my full size processor as I can use it to make small amounts of tapenade or pesto instead of dirtying up the big processor. The immersion blend stick works perfectly, makes my refried beans the right texture, blends vinaigrette in short order and cleans up well..just be sure to watch the blade, it's sharp but that's where the 'stuff' hides during wash up.
We are pleased we purchased this item. Often can be used instead of a counter-top blender. Produces very smooth results with far less mess to clean up.
Clean up took only seconds - even including disassembly. I would recommend this for anyone who loves to cook but doesn't have a lot of time to deal with the preparation and clean up involved. It's easy (and fun) to use.
The best thing ever. A must have everyday product! It is so great, easy to clean, sharp, extremely powerful- I made a large cheesecake using this and did great job. I use it for sauces to blen vegetables in so my kids don't see them and many more. I highly recommend this product.
I had purchased a cheap stick mixer and really found it so useful but the motor would over heat and burn my hand. I purchased this one with all the attachments and it's my prize tool in the kitchen. It doesn't get hot and it has practically replaced all of my chopping and mixing tools. Thinking about getting one for my mom for Christmas.
Answer: I fill the contained I used with soapy water and whip it up with the smart stick.  Cleans very easily.
