I bought one of these a couple of years ago - full price - and found it to handle all my hedges easily. It was a lot better than the Ozito (??I think) that I had before. The cheapie struggled with all but the thin stuff and vibrated badly. Not as good as a Stihl, but not the same price either.
NOT cordless BTW.
With that price drop I am guessing Bunnings are running these out so they probably won't last long.
Bunnings blurb:
This Flymo 500W powerful electric hedge trimmer includes extended reach and double cutting blades for a neat finish.
Double cutting blades - Diamond ground, double-action cutting blades that deliver sharp, neat cut and superior finish
Blade Brake - Features a safety blade brake that stops the blades in 0.5 seconds for optimal safety
Central Handle - Unique central handle design provides the user with a comfortable and safer working position
Blade Guard - Transparent guard for increased safety and visibility. Light weight design ensures easy manoeuvrability and reduces operator fatigue
Belt Clip - Spiral, self-retracting cable features a convenient belt clip, which ensures the cable is kept away from the cutting blade
Flymo is a part of Husqvarna so should be decent!
