The second one ran for an equal amount of time and it didn’t stop before my job was done, so I would recommend getting a second battery if you have ( like me ) a very Large area to deal with. Started with the smaller one which ran for a very decent 30 minutes and I noticed that it didn’t drop off in performance as it reached the final cut.basically it just stopped. With regards performance, well I was very impressed. The wheel guard was probably the most difficult to get attached but not insurmountable. Building the strimmer was pretty much self explanatory using the visual representation, I also like the way it is put together which makes for comfortable handling, there are 3 angles to choose from which are initiated using the red flip it round peddle. I charged them up prior to trying it out and both took a minimal time to do so, both fitted the supplied charger. The battery which came with it 2.5 AH which I considered to not be enough for my needs, so I purchased the 4.0 MA one also, both are 18volts. ideal if you don’t or even if you do have access to power. Like an old fashioned scythe V shape which was very obviously the clear winner in my opinion, feels very user friendly.

I went to B&Q to see this strimmer and was immediately taken with it- ergonomically speaking. Only got the chance to use this today- a couple of weeks after purchasing.
