I've bought a Parkside 40 Volt Hedge Trimmer / Cutter, How heavy is it compared to my old machines?

I bought this hedge trimmer as i was curious to know how good it was, didn't really need it as I already had 2 machines. As you'll see from the video the 40v strimmer have a good long cutting bar, It still weighs much lighter than my petrol strimmer.
My honest opinion is that this strimmer has me converted from the petrol machine to battery operated.
Parkside 40 volt is... 1* Lighter to carry.
2* No emissions or fumes.
3* just add batteries an go.
4* Simple to use.

I am into battery also. Thank you for the advice about the 4 amp.
