Overview:

Keep the check engine light off with MagnaFlow California Grade CARB Compliant Direct-Fit Catalytic Converter 4551603. 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 2003 GMC Savana 3500. The included gaskets & hardware reduce the possibility of a leaking seal while avoiding the need to reuse corroded factory parts for installation. This replacement part is designed to meet or exceed California Air Resource Board requirements, and has undergone additional testing to be certified by CARB for legal use in CA/CARB restricted states for the listed vehicles.

Edging made easy
Size: 9 inches
Surprised how well this works. I was looking for no cord for long driveway. The battery takes a bit to fully charge, but lasts for the entire job. The levels for depth make edging around d flower beds or raised beds easy- not really a trench, but gives a good edge. Lightweight and easy to manage. Definitely lighter than my corded edger. The blade is sensitive and the guide to keep it steady along concrete is not great- just need to make sure you watch closely or it will spark when it hits the concrete.

Works well, a little under powered
Size: 9 inches
Works well, a little under powered when I used it for the first time. Once you get the groove established it works great to maintain it

It’s junk
Size: 9 inches
Deserves a zero. Like some others said on here, it runs for 3 seconds and just stops with battery fully charged. I got it for Christmas so too late to return. More China junk.

Great price, does a good job
Size: 9 inches
 I’m mostly old. School when it comes to yard equipment. A gas engine has got to be better than a battery . I have  a weed eater that will take out a tree but makes a lousy edger. Since I  don’t have a large lawn, I gave this guy a try. Turns out it does a pretty good job. Can’t beat the price and it’s simple to use. Be aware, this vendor sells the unit only. They have no spare parts and you will need to source replacement blades. ( they supply 1 spare). Otherwise, worth a try. John J Why did you pick this product vs others?: A cheap price and a limited need.

Not too bad for the price
Size: 9 inches
I was skeptical if an edger as cheap as this one would do the job at all. I figured if it worked at all it might be worth the price. I was surprised be it is actually pretty good. I have a medium sized area. Just one driveway and about 30 feet of sidewalk. I will use it four or five times a summer and I expect it will last for a few years. It hold a charge enough for my needs. If you have a large driveway or plan on using it every day, you will probably be disappointed. But if you have a small area to do, its not bad.
