HDI, German Auto Ins. company, from Parker Ins. lakeside

Is HDI sold lakeside in additional to Parker? It covers $150,000US / liability for the North America and elsewhere in Latin America. In 6 years, they have had one Canadian claim for the liability and I was told HDI paid without a problem.

I'm wondering if anyone on this board has HDI?
If you have made a claim within or outside MX; their response, ease of dealing with the company and payment or not?
Qualitas also has the outside-of-MX liabiity insurance ... does anyone know how that might compare to HDI?

Thanks ....
