"I looked at the Black %26 Decker web site and found the exact product for the same price as Walmart was selling it except Walmart showed a $20 discount on the product when the ""discounted"" price at Walmart was the same exact price at the Black %26 Decker web site. The $20 discount was a marketing ploy. Shame on Walmart for being deceitful!"

Great Idea!

I must say this thing is perfect for a person that has a small yard and not to much storage space.. My kids have toys that's heavier than this thing.. It also has a wheel attachment for edging to make it simple to use for someone like myself that never did it.. The question would be how long will it last because it really does feel like a toy.. But for $100 you can't beat it

Crisp Versatility

Really like the versatility of this design. The edging guide really makes my edging crisp whether it be the driveway or those strips of grass outlining the neighborhood sidewalks. The mower clip in is also great for catching those quick weeds. Assembly is super easy. You really just have to place the handle.
