Easy of use.
Easy to use for edging driveway. I am not a professional and a senior who is learning to take care of my yard.

Nice Edger as long as the blade doesn't come loose -- and it will come loose, repeatedly!
Probably could've/should've rated this 2 stars yet it works well when it works. I purchased this edger to edge my drive and sidewalks and not for trenching. The edger arrived very quickly after I ordered it (I am not a Prime member so this was a nice surprise). Assembly was easy and straight-forward. The first use went smoothly and the edger performed flawlessly and provided clean, smooth edging. About 20 minutes into the second use I noticed that the edger was cutting and quickly determined that the blade was spinning freely -- fortunately the hex nut was still attached to the threaded shaft. I reviewed the manual that came with the edger, grabbed the correct sized socket and torque wrench. I removed the hex nut, the first washer, the blade and then the second washer. To install I followed the directions ensuring that the flats of the washer aligned with the flat on the shaft and tightened the hex nut to the specified 140 in-lbs. The edger worked well for about 10 minutes and the blade once again became loose. This time I replaced the original blade (which did not need to be replaced from a wear perspective) with a new B&D blade and new washers. Once again I followed the instructions and this time the edger performed flawlessly until about 5 minutes remaining in my edging when once again the blade came loose. my experience has most certainly been frustrating to say the least. one should not need to carry a socket and torque wrench with them and repeatedly need to tighten the blade. So, when the edger performs as intended it does an excellent job at edging; however I have no confidence that this edger will be able to perform as intended throughout repeated uses and more importantly has shown that it cannot complete my edging without requiring tightening the blade (which requires disassembly down to the second keyed washer). Potential buyers should be prepared for this experience and make your decision accordingly. Note: I tried contacting black and decker via twitter (@blackdeckerhome) and never received a response; I could not find a separate customer service/support twitter account. Trying to contact customer service via the phone these days is an exercise in patience to say the least.

Great edger for home use
This WORX 12 Amp Electric Lawn Edger did exactly what I needed it to do. It was easy to use, had plenty of power for cleaning up the edges around my driveway and sidewalk, and gave the yard a much cleaner, finished look. I like that it is corded because I do not have to worry about batteries dying, and it has enough power for regular homeowner use.
The first pass took a little extra time since the edges needed cleaned up, but once I got going, it worked great. Overall, this is a solid edger/trencher for the price, and I would definitely recommend it for anyone wanting cleaner lawn edges without dealing with gas.

Little work horse!
I LOVE the look of an edged sidewalk. After a few calls to some local landscape companies, I couldn't find anyone with an edger. Crazy! So I bought myself this one! Super easy to put together and just as easy to use. My walk hasn't been edged for many years and was very overgrown. I was nervous that I wouldn't be able to run this thing, but this little work horse did the job for me and did it perfectly. It will be super easy to keep it edged now. Extremely happy with this purchase.

Takes The Edge Off!
This is a decent product. If you are going to do a lot of edging, or want to do deep trenching to run conduit, etc. this is NOT the product you want. It is electric, so you are tethered to an outlet, and of course, the farther you go on extension cords, the less of the 12 amp juice you get. It also trenches to 1 1/2", which is OK, but not enough to dump conduit, etc.
That said, this is a very good edger. Out of the box, it is minimal assembly. You connect the three pieces of the shaft, removing some edge tape from it, and inserting two metal bolts and plastic knobs, similar to most lawn mowers these days. Then you install the plastic handle with another bolt. That's it.
For use, you have a lever which you pull up for edging and lower for trenching to adjust the group clearance. You also choose 1", 1/4", or 1 1/2" depth. Then you plug it in.
There is a white line on top of the blade cover so you know where the blade is. You just pull the trigger to run the blade, or release the trigger to stop the blade.
Be careful not to lose sight of your electric cord so you don't hit it!
I edged along my driveway, about 50' on each side, as well as my front of my lawn, so another 85' along the lawn and the apron (both sides). That's over 350'. It cut through the grass and dirt easily. It struggled a couple of times, on some tough mounds of grass, but like any other tool, you don't force it when that happens, just back up and do that area again slowly.
If you come too close to blacktop, Belgian block, stone, etc. you will see sparks so you will know.
Just keep in mind, this is an edger. You will be left with the severed grass/sod to remove. In my case I was loooong overdue for a edging, so I spent a long time scraping the sod off the pavement with a shovel. I expect with more frequent ending, and now working with a cleaner edge, this will be less of an issue. Either way, that is not on the product, but the state of the lawn.
The edger has 2 read wheels and one smaller front wheel so , although this is not like a big, gas-powered curb jumping unit, you have the option of attacking a curb edge from either the blade side or other side of the edger, so you can get real close to a Belgian block curb.
I also did the edge where my grass meets my mulched flower bed, but that was more of a trimming than a edge removal.
Overall, the Work edger did as good, or better, a job than my string trimmer, and I didn't have to stop every few minutes to rewrap string. Plus it trenched enough to give me a definitive edge, whereas the string edger just cuts into the grass, not a real trench.
