Document: Just be sure to shop around to make sure you're getting the best price. ALSO SEE: The Benriner Cook Help, or Benriner Cook's Helper or Benriner Asian Spiral Slicer.
The Cook Help we were going to return but ended up giving it to my mother in law and in the interest of science we tested both units. So now I can write what may be the lone review comparing the two units. (She was here while we did this, it wasn't a case of we used it and then said "Hey, here's a present for ya!" - just so I don't sound rude or anything here, LOL)I did some zucchini on mine, with the medium blade.
This slicer is far too difficult for the job it is trying to do. I have tried to make it work a half dozen times and it just is too challenging. It doesn't hold the veggies tight enough, or they wobble or they fall off. Definitely not a tool to use if you want to work quickly. I recently bought a new handheld spiral cutter.
I had some zucchini angel hair with pesto at a potluck and was so amazed by it, I have been seeking the right tool for the job ever since. The little Joyce Chen gadget many seem to rave about gets such mixed reviews, I was afraid to try it. When I came upon the Benriner, I was sure I knew which brand I wanted - but was not sure whether I should go with the cook help (upright) model or the horizontal model.I couldn't really find anything comparing the two.
As if it were possible, I've actually found another spiral slicer that I love even more! The Benriner Turning Slicer is very similar to the Benriner Cook's Helper, you'll often find this higher end model in restaurants. Benriner Spiral Slicers are ALL extremely reliable each of them offering true versatility and durability. These models are made of ABS and Nylon reinforced resin, this spiral slicer is here to stay!
I love my new slicer. It has become a very important tool in my kitchen. I use it to "spiralize" vegetables for my soups and salads. It makes being RAW more interesting. The slicer is so easy to use . . . if you have children they can help prepare dinner simply by turning the knob . . . like magic noodles are created!
I've had my turning slicer for a few years now and it makes the best raw veggie noodles ever. I love using it for zucchini, beets, carrots, celery root, and more. It comes with multiple blades so you can have different size noodles. My friend has the same one and she loves hers, too! I recommend it to all of my customers.
I purchased the Benriner Turning Slicer under recommendation of health institute class. I love it! It is a tool that is mandatory for eating raw! (along with vita mixer, excaliber dehydrator, & juicer)  This is the one that the professionals at the health inst. use in their kitchen at home. I would never have a different brand. I invested a Fortune in all of my equipment & do recommend this brand only. Mama L.
This product was amazing, I loved it and use it every chance i get especially when I have guests over. Thank you!
You can also expect to replace your blades at some point during the lifetime of your Benriner, because inevitably they will become dull. Replacement blades are available on quite a few websites (do you're homework because I can't list them here) I've seen the complete set listed for approximately fourteen dollars. I agree with those who say this item is pricey and compared to the numerous poorly made spiral slicers on the market today, it certainly is.
