I've got one of these - bought it last year from Lidl too! I've found it quite good on the dandelions, but I do have to go over them several times before they finally give up, and also they seem to be able to continue to produce flowers after I've given them the once over from the weed gun, as though in a last desperate attempt to propogate themselves! So I actually still have to manually pick off flowers every day, and then go over them all again a few days later with the weed gun - it is a bit time consuming I must admit! I'm of the same opinion though - I really don't like using chemicals. Think I might get a daisy weeder to try and see how I get on with that. It seems that whichever method you use, apart from the old weedkiller, it's time consuming, but the weed gun did work for me in the end, with some persistence!
