I have used all brands out there except the turf tec (sp) side winder. I feel the Little Wonder is easy to allow to get loose or out of line because it's hydro. Now maybe i'm just not experienced enough with it but i made me not even want to learn. Plus it's terrible on slopes. The pull behind (BB Bed Bug/Brown) is easier to maintain control and a tight line as intended. I believe that this is one area not to rush. I'm not saying drag your feet but take your time and install the edge right the 1st time and it will save you time later. IMO, the Bed Bug has fit the bill the best for me.
Believe nothing that you hear, half of what you see, know that most people are idiots!
