Like you Mokey, I liked the old but was reticent in using it because of the speed... Much as I hate gardening, when I cruise the jungle, the new one is always in hand to clear the path... much like the machete by jungle travelers.
It's the concept I'm spruiking rather than the brand... you don't have to be old to relish in the convenience, however it helps (to be old) to have fit enough fingers/hand at the end of a gardening session to hold a glass of vino.
The beauty of these is that I'm sure there is one to suit the type of batteries people have... what I'm trying to emphasise is to read (UGH) and consider the operational cycle before you make a purchase.
Pottzy, you may need to read this a few more times as there are heaps more puzzles to follow.
If your first cut is too short... Take the second cut from the longer end... LBD
