Acceptable because I didn't really get what I thought I was getting but after having similar problems with Euro car parts I lost the will to live and couldn't be bothered to send the parts back again. I bought two windscreen wipers for my car. One of the ones from Euro car parts was the wrong size so they had to go back as they were sold as a set. The ones from GSF were sold individually and were both the right size but they fitted with adapters not directly to the arms. The photo of the parts from GSF showed no adapters and a neat direct fit. They work just fine but the adapters are clearly visible when driving and thus annoying. I suppose I'll get use to them but they were not as shown in the on line catalogue!!
