If you've only just got it I should try and get a refund. As the others say they seem to have a problem since a manufacturing change. I have the 12" Silent "Runner" - it's great - totally silent and spins really easily, plus it has a nice sturdy base. But it's a bit expensive to buy in the Uk due to import charges. The Trixie wheel is a cheaper option - not silent but most people seem to find them fairly quiet. It's 28cm so not quite as big but big enough for most Syrians. The Trixie wheel is a bit flimsy in comparison but it does the job!
