First, thanks to Neptune Systems and BAR for providing the opportunity for me to win this art the raffle. Second, I got it set up today and thought I'd give a quick report on the unit. It's awesome! I've set-up a couple of other brands of ATO's in the past and this is by far the most solid, well-built, well thought out unit I've seen. There's a two minute video online that shows you how to set it up in less than 5 minutes -- and you can! It actually took me longer than that because I had to run tubes and wires behind my 6 foot stand and to a couple of different sides. If not for that it would be a five minute set-up. Clicked it on, adjusted the sensor height and boom! -- it worked perfectly. I love this thing! Best one dollar I've ever spent (on the raffle ticket.) However, it's worth every bit of the $200.00 price tag. At that price it's comparably priced to the Tunze which is considered the best choice by many and this is much, nicer and safer.
