Product review (5 stars): Love it so far
I was very hesitant about purchasing this at first and actually debated it for several months because I couldn't find any stores that sell it and was not able to see it first before buying.  Finally, the many positive reviews swayed me to purchase it and we did.  It arrived in working order, was fairly straight forward to install.  The instructions for mounting under the cabinet are not good at all, but you can figure it out.  It came with some bolts that were not included in the instructions at all and that is what I used to mount it.  It did take 2 people to mount and also a very long wrench extension as you can't fit your hands up to tighten the back 2 bolts.  The product is fabulous, does exactly what it says.  We tested the gas leak sensor and also auto-on features and they both worked perfectly.  And the suction power/fan is great.  An equivalent with another product would easily be double in cost.  We are SUPER happy with the product.
