I bought two, one of them broke (1 of 3 contacts sank in, no way out of the ignition without opening the unit (under warranty!) And push the inside slide gently if it is not too far or it will break that was partly the case). Does the job but has only pay for ... Too bad the Sony model is so expensive, and it is not perfect either (false contacts!) So what to do? For my previous Sony, I had bought two other contacts and only one of the three had the same problem, need to open it and push the slide contact, so I would say it contacts fragility problem recurring with this supplier.
