Well, I dont think anything is wrong with it. It's just not worth paying for. The jobs that I found in there were certainly interesting too. Since the fee is not too much, if you are looking actively, it might not be bad to subscribe for a month or something.
Edit: Btw, I had paid on the German site at the time (www.experteer.de
). I think you can still access the jobs on the swiss site, and I think the euro payment is cheaper.
