I bought an Aldi petrol driven lawn edger on a Saturday special deal, $189. It started first pop after adding petrol and oil but it has insufficient power, the blade keeps stopping. Also there was a small note on the outside of the box I did not notice till I got home " not suitable for curved edges". My test was on straight edges though.
I returned it to Aldi and they were brilliant, no fuss, very professional, my thanks for that!
