This is my first edger and as long as Black and Decker keeps making it, I will only buy this. If, I need a replacement. I have this for over a year and it always does a superb job of edging. I am not a believer of electric or battery operated tools for landscaping and only use gas powered engines due to their power, but this has been an exception. I love using this and it took care of my doubt about it being underpowered. It is powerful enough to tackle few weeks of growth and makes clean/sharp edges. I also have professional gas powered weed-wacker, but I was never good with that and always messed up while trying to edge, but Black and Decker LE750 is idiot proof. Go for it and you will never regret it. However, I did pay considerable less amount at Sears, than what Amazon is selling for.
