Product review (3 stars): Some Issues
I have own this cook top for over a year now. Here are some of Pros and Cons I have experienced with my cook top. This is my first gas cook top.

PROS
1. Very nice appearance and stylish.

2. The large center burner boils water faster than my electric, maybe due to the fact, that the heat is instance. Other burners perform well for cooking and simmering.

3. Easy to clean, but see below.

4. Was not hard to install.

5. I like the light indicator that shows that a burner is on, this was important to me being that this was my first gas stove top. It was difficult to find this feature in this price range.

6. It has a re-light feature, if the flame were to blow out, the unit senses this and re-ignites itself.

CONS
1. The large center burner takes a long time to light 50% of the time. I contacted Bosch support, and now that the unit is out of warranty, they cannot suggest any fixes except to have a service repair person come look at it on my dollar. I get better support with a lot of older appliances and products I have.

2. I have a round bottom wok, and for years and perform well with our electric cook top, but does very poor with this unit. For wok cooking you need lots of heat. The center burner just heats the sides of the wok, not the center. I contacted Bosch about this and they did not have any recommendations. So I bought one of those rings to place my wok on top of, but now there is just not enough heat. It probably raises it too high. On suggestion for another reviewer,I may try a nontraditional flatter bottom wok.

3. It is easy clean, but has developed some brown staining around the burners that are unsightly. This is probably spillage that has been baked on, but is going to require some extensive elbow grease to remove.

Overall, It's decent unit. You may want to think twice if you do a lot of wok cooking.
Bosch could have better support services.
