Comprised of multiple embossed layers of stainless steel with the outer layers utilizing a Viton rubber coating. Compressed operating thickness is 0.040". Cometic MLS (Multi-Layer Steel) Head Gaskets provide maximum sealing performance for todays high output engines and require no sealants. MLS gaskets are ideal for both aluminum heads to aluminum blocks and aluminum heads to cast iron blocks. They can withstand the shearing force created by the two materials. MLS gaskets have increased strength because they are comprised of multiple layers of stainless steel; which also creates the ability to rebound and resist corrosion. The outer layers are embossed and coated on both sides with Viton (a flour elastomer rubber based material that is heat resistant to 250 C/ 482 F). Viton is designed to meet the demands of a variety of harsh sealing environments, load conditions, and surface finishes. The center or shim layer is uncoated stainless steel, which can be varied to accommodate multiple thickness requirements.

Stopped cutting cans after 31 days
Color: Green
This quit working exactly 31 days after delivery. Since the day of delivery counted as day 1, I am out of luck on my purchase.

Mixed results using this auto can opener...
Color: Green
I had high hopes for this can opener, but was let down. This can opener failed me half of the times I tried to use it. For some reason it wouldn't cut through the paper surrounding the cans. I tried it on small, medium and large cans. It worked best on larger cans. I got it because I liked the idea of opening cans without having to contend with the sharp lids that inevitably fall back into the opened cans. It is unsanitary at best and a safety hazard at worst. On the plus side it is rechargeable, so no battery worries there. It fits nicely in the hand for ease of use. It appears to be of sturdy construction, so it's a high quality item. And being small it will store easily. The price is right and it represents a good value for your hard earned dollars.

Hands Free Operation; Safe Cutting
Color: Green
I used to have a manual (as in turn-the-crank) side-cutting can opener really liked it. It eventually wore out and I had relegated myself to the standard hand-crank top-cut version that often left a sharp lid and sometimes a little burr or sharp point where the cut wasn't complete and the you had to the tear/bend the lid off. With this mostly hands-free Side Cut Can Opener, sharp edges will be few, if any. I say "mostly hands-free" because you do have to position the opener on the can and push the button to start it and, when it finishes, you have to push the button again to tell it to stop. On the demo can in my video, the lip was such that the cut was right through that edge such that there were no sharp edges. It is possible that some cans may be designed such that the cutter falls below that rim and cuts the can edge in a way that leaves dull lid but a sharp can. These should be rare, but good to watch out for in case you get one. Always assume edges are sharp until you verify otherwise. You'll note in my video that the lid was a little difficult to remove. Some of that may be learning curve with this new opener, and some it may be that is just how it is! I accept that and choose to move forward using this new, safer can opener. Recommended.

Very dangerous metal shavings!!!
Negative stars if I could. This is a very dangerous product. It worked well for a while. But then it quit effectively removing the lid instead I got little tiny shavings of metal around the edge. These shavings of metal go into the food and very dangerous. So this was a waste of money and incredibly dangerous. I am throwing it in the trash today.
