Fractional CO2 laser for fine lines. Is the Lutronic machine good for this?

I'll be visiting Vietnam for vacation and thought I might as well get fractional laser treatment for my fine lines (while I have the time off for my skin to heal.) I looked into a dermatology clinic there and asked what kind of laser they use for fractional laser treatments. They replied that they use a machine called "Lutronic". They suggest 3/4 treatments for optimal results. Is this a good, appropriate laser for the job? It's always scarier doing things abroad,so any advice is appreciated!
