Alientic, I would also like to let you know about a few changes we have made with our Cool Cab. I know that SLS said the temps should be up to 87 degrees but from the beginning, the high temps concerted DJB and I so we: added another duct fan to pull the air from the light tube on the opposite side. We also purchased a larger exhaust fan to pull the air and as of late we have direct ducted to exhaust outside (we are on a slab so the exhaust goes under our home), no noticeable smells at this time, if it becomes a problem, we will try putting the cabon filter at the end of the exhaust hose. I don't want to complain about SLS because of the great results we are having, but I don't want anyone to think that you can actually turn the key and bamm, it does all the work. Before exhausting to outside, we left the doors cracked to control the heat and what a smell, having a few teens around we have to be very, very careful. Honestly in my lack of knowledge I truely believed that the cabinet would look like any other cabinet in your home. LOL !!! I call it the spaceship. I have contacted the company and told them that I believe their product have great potential, but that I feel that they have skimped on some key components of the cabinet. We also have been using the CO2 boost from very early on. You can purchase it a bit cheaper on e-bay.
