I
I'd like a cordless trimmer and wonder about an electric one as
opposed to
a petrol one.
Seems then that cordless electric would not do the job properly in one
session.

I have a Stihl petrol trimmer, which has been excellent, for quite a few
years, however due its weight and the fact that parts of my beech hedge
are high and fairly inaccessible I bought a GTech telescopic cordless
trimmer which was on offer through the Telegraph last year.( See
http://www.greytechnology.co.uk/HT01.php) I have found it very good,
especially for trimming soft new growth. I also bought a second battery
but so far all trimming has been done on one battery which is worn on a
waist belt.

I can recommend the cordless trimmer however it could not cope with
thicker, woodier growth which is where the Stihl comes into its own.

Hope this helps.
