Overview:

Keep the check engine light off with MagnaFlow OEM Grade Federal/EPA Compliant Direct-Fit Catalytic Converter 51084. With features including free-flowing mandrel-bent tubing and highly corrosion resistant, stainless steel construction, easily install this spun body converter yourself using the proper tools, no cutting or welding required. MagnaFlow's state-of-the-art metrology department uses the latest 3D scanning systems during research and development, so you can be confident that your new part will fit and function like the original equipment. By replicating the OE spun body design, the single laser fusion weld greatly reduces the possibility of a leak, and our compact, low-mass design also allows for greater thermal efficiency. This direct-fit catalytic converter is designed specifically for the 2001-2003 Audi S8 and interchanges with OE parts 4D0 131 090 RX, 4D0 254 550 AX, among others. Hardware is included to eliminate the hassle of working with corroded factory parts.

Smooth edges better than twisting
Works a lot better than the crank style and the counter top electric and you can use the lid to reseal the can if you don't use the whole thing.

Worked for only 4 months. Now produces metal shards. Dangerous
Pros: Can be used with one hand. I bought this to have after surgery that left me without use of one arm for a few months. The light blinks when you need to charge it. Only needs a 2-3 min charge for enough juice to open a can. Cons: IT QUIT CUTTING CORRECTLY AFTER 4 MONTHS. I now have to use both hands to hold it in place to get it to latch on to the can. It also requires a few rotations around the top to cut through the seal, resulting in METAL SHARDS! The metal shards are super sharp and almost invisible. I stabbed myself with one enough to draw blood. This is dangerous as the metal could fall into the food when pouring from the can.

Can opener
This product does not work well! It actually doesn't work at all!! Will not cut thru can lids at all. Very disappointing to say the least. I purchased to make things easier only to be left not being able to open dinner 😕. Would not recommend to anyone!!!

Can opener
It doesn't shut off by itself when done and doesn't shut off when I push the button, so after a while it will shut off but when it wants too after you take it off the can ,like 30 seconds. But I do like the way it cuts, a clean cut and lid removal nice.

So simple to use, I'm amazed
Color: Black
Wonderfully helpful. Description is accurate, shipping was quick. I saw a few poor comments, but I have none so far! The can opener has opened cans of several sizes, from tomato paste to large cans of tomatoes; soup cans to strangely shaped. It's opened 30 or so already without loss of power. It's a little noisy, but about equal to that of a stand up opener. It fits in my drawer, which is less deep than most kitchen drawers. Most of all, it's beyond easy to use for arthritic hands. The ONLY CHALLENGE I have is that it sometimes fails to stop when it should. MANUFACTURER: if you read this and have advice, please share. At this point, I'd say this is a great value for the money.
