Product review (3 stars): Convenient and portable but heat is a bit unevenly distributed
This was my first time using any kind of portable cooktop and I found the experience to be a mixed bag.  On one hand, I love how lightweight and portable this is.  I head up a breakfast club at my work and since we don't have an on-site stove I loved that I could use this for preparing breakfast there.  It's easy enough to tote back and forth from home (even on public transportation) or if I choose to leave it at the office, takes up minimal space.  But, the cooking experience isn't as good as using a range.  As others have mentioned I definitely missed the fact that the burners weren't used to what I have at home and the slightly uneven temperature.  The latter was actually the bigger burden of the two because it was noticeable even using it with high quality quality cookware known for heating evenly.  Because of this, it has taken a little adjustment to learn how to cook well with this portable cooktop so I personally wouldn't use it straight out of the box for a big or important meal.  I'd recommend playing around with it a little bit first.
