Experience with APP TUTTI ?

Hi guys

I think most of us Android developers got the (spam) mail from APP TUTTI.
Does anyone use them?

Their service looks quite promising. We need to add their SDK and they put the app to several app stores in China.
Seems like it is possible to use banner ads and in-app billing.

Looks like a quite good option to enter the Chinese market.
Unfortunately I haven’t seen how they do the payment and what their revenue share is.
Besides that, it is questionable if we can trust such a Chinese company. It would be extremely easy for them to cheat.

Any thoughts?
