Ok hopefully my last update on this matter, trying to put a lid on this issue.
I had good communication with my local store and I went there so we tested the universal adapter. It was a powerking 1200mA adapter, don't know how common it is. Anyway we set the adapter to 7.5 volts starting low in compare to 8V and used a proper connector with plus in the middle. It worked so I bought it. I have now fully loaded the mx1000. The adapter didn't even get hot nor the charger. No weird smell or so. So it's solved. The only thing I can complain on is that there is a glitch between th connector and the charger. You really have to tune the connector to make the charger charge the mouse.
By the way I still haven't got a bep from logitech support. With other words pray you don't get trouble with a logitech product and need to contact them
