Question: One of the brass screws broke on my unit, how do I get warranty repair on the 6 month old cheese cutter?
Document: Hubby is a cheese hound and his old cheese cutter broke--as I'm telling him not to use it on Gouda with rind. After much research this cutter came out with the best ratings and we/he are pleased. It is heavy. The wire seems good and substantial and it cuts well. We have not used the adjusting aspect thus far. It is being tested daily on aged cheddar and I would recommend it.
This should be the last cheese slicer I ever have to buy. I have been trying to get away from products that were out and break. Plastic cheese slicers break, the wires snap and the screws rust. I noticed this was heavy and solid. it's made of aluminum and brass to prevent rust. it also comes with replacement cutting wires....nice. it adjusts to slice different thicknesses. This product shipped on time and in good condition.
I had this slicer for several years, and it is my all-time favorite. You can adjust the wire to get very, very thin slices, as well as much thicker ones. I don't know how thick the other reviewer wanted their cheese slices, but this thing can go far thicker than I'd EVER want on my sandwich . . .My only word of caution: DO NOT EVER put this in the dishwasher. The brass screws that hold the wire in place will corrode and break, which means the end of the story.
Specs show that it "measures 5-2/3 by 5-inch," which is correct. But the brass side screws needed to be adjusted with a pair of pliers. The wire on this broke in less that a year, so checking with the Swissmar site found that the listed a "Wire replacement for # D1024 Dalla Piazza branded Cheese Slicer. Also fits Swissmar branded Adjustable Wire Cheese Slicer #S3009. Just undo screws on the sides of the slicer, replace wire, tighten screws." Cannot locate this here on Amazon, so it's sitting in the kitchen utensil drawer until I can pick up replacement wires locally.
I got this because I wasn't paying attention. I typed in "Trudeau cheese slicer" and figured that's what I would get. I had my Trudeau for years and it was absolutely THE BEST. But apparently it isn't made anymore and Amazon is referring people to this piece of junk. Most cheese slicers break after working well for a while. That's what happens with the Oxo models. This misbegotten tool of destruction just doesn't work period. On the other hand, it appears indestructible. I had to put mine in a machinist's vise and beat on it with a 22 ounce framing hammer to get any satisfaction from it.The brass screws attack your hand if you have to hold the cheese (and you do.)
From the picture, it looked like a sturdy unit that would keep the wire tight for a clean straight cut. As-delivered, the wire was loose and continued to get more loose with use. There is no provision to tighten the wire. Wire finally broke and now I'm shopping for an alternative.
My son was trying to adjust this tool after we had owned it for about a week. The roller wouldn't tighten properly. He used a little more force and it broke. Before it broke, the size of the roller was an issue. The block of cheese being sliced would chill the roller. Moisture would condense on it. Thin slices would stick to the roller and get wrapped around it. Our old slicer with a smaller diameter roller didn't have this problem.Not recommended.
This one is a 3-star utensil.&#9670; Summary:Have no complaints with thisNorpro Cheese Slicer(Model #330) so far. It's comfortable to use, well crafted and has a decent finish, making it easy to clean. The roller action is very smooth, and the brass side adjustment screws hold quite well, with a good range of thickness for cheese slices. The stainless-steel cutting wire is still tight after months of use, and it does come with a spare wire in the package in case the original one breaks.
This one is similar to my old one, but not as well made. The slicer does not tighten as well as it should. I would not buy another one. Plus, I still need to get a usable cheese slicer.
After looking at lots of models, this is my favorite slicer. I used an old one until the wire snapped. This one came with a spare, is compact and above all, does not have too many nooks for cheese to get stuck.Absolutely love it, and it is easy to change the wire and thickness of the slices. I use this with a relative soft Gouda cheese from Costco and it works great.
