Product review (4 stars): Good value for the price.
First off, there are some things to be very aware of.  I have no knowledge about this subject so I am not giving you advice.  Below information is for entertainment purposes only and should not be considered advice.  Anything you do is at your own risk and I have no liability.

1.  This cooktop has the european standard threading on the connections so you can't connect to US standard without an adapter:

  I also used a female BSPP adapter to Male BSPP flare that windmax sent me.
2.  The gold rings in the center are metal and can't take the heat without discoloring.  Windmax sent me replacement black ceramic disks for center burner.
3.  The cutout for this was much smaller than my previous cooktop but this may not be the case for yours and certainly not an issue for a new install.
4.  I bought from Windmax and support via email was good.
