Overview:

Keep the check engine light off with MagnaFlow OEM Grade Federal/EPA Compliant Direct-Fit Catalytic Converter 21-170. 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 2009-2016 BMW Z4 and interchanges with OE part 18 30 7 647 041. The included gaskets & hardware reduce the possibility of a leaking seal while avoiding the need to reuse corroded factory parts for installation.

Great battery powered edger
Style: Lawn Edger w/(1) 4.0 Ah Battery
This edger works great love the guide for along sidewalks and curbside lawns. It is a little underpowered for really thick lawns battery goes down fairly fast on the thicker areas but all in all it’s great

The blade is not sharpen.
Style: Lawn Edger w/(1) 4.0 Ah Battery
I had no problems assembling the equipment. The problem is with the blade. It doesn't have any sharpen. I bough spares blades which have a different configuration and better edge. However I haven't been able to unscrew the bolt in order to install the new blade. It is extremely tied. One would think that you purchase this equipment, at a high price, and would be able to use it right away. In your dream. This is a Third World Country selling things at an incredible high prices, for the profit of the American companies using the manpower of other Third World Countries or China. Since the blade is not sharp, when you try to use the equipment it got disconnected. Therefore it does not work with the blade that comes from the manufacturer. Total disaster.

Worx very well!
Style: Lawn Edger w/(1) 4.0 Ah Battery
Worx very well. ;) More power than I expected from a 20v cordless machine. And with the 4Ahr battery it comes with, I was able to do the drive, walks, and patio without having to change batteries. I own 2 Worx string trimmers, chainsaw, hedge trimmer, drill impact driver, and leaf blower. Love them all.

Problematic instructions
Style: Lawn Edger w/(1) 4.0 Ah Battery
The product is great once u figure out how to assemble. The instructions don’t do it. I was not happy. Every part was a challenge. The instruction book only shows a photo but not how to get it to look like the photo.
