Input:
Question: how long of potato and how round
Document: My husband barely touched one and sliced his finger. I haven't had this long, but this thing is HEAVY DUTY! I imagine it will last for years, and only the blades will have to be replaced and/or sharpened. Highly recommend!
This product works great, good quality. Bust size is 14inch long, and handle is 10 high as installed. Very big. Handle gives a lot of leverage and suction cup feet are very good at holding in place. RVKitman.com approved.
Easy to clean. Supplies needed leverage for sweet potato fries. Performs very well.
this is totally awesome it's strong,sturdy,from PA anyone ever have Potato patch frys from Kennywood amusement park just like being home great
Use this french fry cutter a lot and really like it! My only complaint is if you have a large potato it can be quite difficult to cut unless you have the suction cups set very well. Other then that it works like a dream. would definitely buy again!
Also, the piece of metal that you lay the potato in ended up getting bent on the first shot. After being left with messy sweet potato fries, I had to figure out how to clean the fry cutter. The only way to do so was to remove the end piece and when I did that the whole thing came apart. After my first experience I decided to return the product.
I read the reviews here and on other cutters like this. Some reviews indicated modifications were made to improve this cutter. At first I scoffed at them but have noticed one mod which makes sense. The plastic washers which limit the travel of the "pusher block" are two small. If the pusher goes too far it leaves a chunk of potato stuck in it which is a pain to remove so holding back a little and pulling the frys out eliminates the problem.
I ended up getting an email from New Star about why I returned it and when I gave them the information in this review they said that this product was not meant for sweet potatoes and as far as cleaning, it is meant for more commercial use where it would be used in a kitchen etc. where it would be used multiple times before cleaning. This may cut regular potatoes well but I would not recommend it if your sole purpose is for sweet potato fries.
I bought this because I figured it would work with sweet potatoes since it is considered &#34;heavy duty&#34; and other reviewers said they made it work with sweet potatoes. On my first use, I split the sweet potato down the middle to make it easier to push through the fry cutter. I didnt have trouble with the effort it took to push the sweet potato through but it did not cut the sweet potato well.
works great and i like fresh food it doesn't get any fresher homemade french frys are great ! if i ever need another id buy this again , but its quality made
Answer: A good sized baked potato - 5 to 6 inches long with a good size girth.But the bigger the potato the more effort you need to push it threw.It is a good machine.
