CfMD lionbridge vs 1ClickFactory

Hello everyone,

Our company is going to register it's add-on as CfMD.

We found to companies, who provides test on behalf of Microsoft: lionbridge and 1ClickFactory.

I found pricing and terms of both, but may be some used them and can give some feedback?

1ClickFactory seems cheaper and gives 5 tries, comparing to the LionBridge.

Anyone with any experience on this?
