Being in customer service for quite a while, I’m EXTREMELY picky about who I deal with. I’ve got to tell you, I’m VERY impressed with the level of support from Comset. Thanks again for your great Service. 
In fact we have solved our problems. We are now enjoying 21st century internet. Your device has performed excellently since installation.
I just want to say a big thank you to Comset. Not only did you get your product to site very quick, the CM820V-W modem/router has been very simple to use.
I’m really happy that it is user friendly with a very easy interface. I didn’t need the manual to start figuring out the factory defaults (IP address, user name/password for webpage login) which saves time.
I liked the way you responded to my question by physically opening up a box and by turning it on.
Overall this router is great, it offers over 10 DDNS websites and multiple user accounts. I was able to achieve everything that I needed it for (VPN setup / DDNS).
Thank you very much! I will be recommending you in the future.
