Product review (3 stars): good and bad
windmax 34" cooktop ; nice looking unit easy to install. Easy was important because the sparker to one burner did not work. We got through a minor language barrier got a new spark controller (wrong one. was for a 4 burner) and then we got the right one for the 5 burner. It was pretty easy to take it apart and replace the sparker. note I am a retired auto mechanic and can fix most things.
Now the things we don't like; The valve controls are on or off. the control at the low end is almost no different than high. Cheap valves.
choosing the right size burner becomes critical for some heat control and we don't like it. We will probably throw this thing away at some point and go buy a $1000. unit after we get frustrated with burning our food a few more times. The removable upper plate diverter and grill come apart nicely for easy cleaning but it is critical they be put back exactly where they should be or you will get a back-flash.
