I see that supermarket chain Aldi are offering a 400W electric grass trimmer as one of their gardening special offers from Monday 6th April 2015.
At a penny under twenty pounds the price seems very reasonable, there are cheaper electric strimmers out there but I cannot think of another at this price that has a adjustable telescopic shaft.
Aldi say this is a new model for 2015. I wonder who is making and suppling them?
This grass trimmer features a dual line bump feed spool and the head angle is adjustable.
