as good as a corded strimmer, run time 25-30 mins.
the double safety catches a bit tricky, and bear in mind battery needs to cool after use before charging, increasing turn around time.

I've not had to use the strimmer for anything more than short grass yet, but it deals admirably with everything I've needed it to.

It's far lighter than my previous petrol strimmer, and for a battery model it's got plenty of power available.

The autofeed has worked fine so far (others have said it's temperamental), although this might change when I reload the spool.
Slightly fiddly to have to press 3 buttons (including the trigger) to fire it into action. This seems to be a new safety measure, but requiring 3 simultaneous presses is fiddly, and if anything makes it less safe given you only have one hand free.

It would be nice if it had two lines, but I did know it only had one when I bought it.

Replacement spools are expensive. I've bought 123m of Stihl 2mm line (for a 10th of the price of new B&D spool & line).

Good power, good adjustability.
The spool does not last long enough. The cord is not robust enough for the power and so is used very quickly, particularly on tougher jobs. A dual use ,swappable, cord and "fixed blade" would be a good idea.
