About a year ago we purchased two Air Shammee II's. Immediately after install I noticed the guns leak from the trigger and the air is weak, even with the air blade attachment. Ive since removed the guns and put regular vacuum tips, the ones you use to get between the seats. They still are so weak you have to hold it right up to the car for it to push any water. Needless to say, barely any customers use it. We didn't even bother installing our second unit its been sitting for at least a year, brand new. Has anyone else had a better experience with these? We had tried to contact Diskin about it but it seems Diskin's support is just one guy and we never hear back. It's way too expensive for such poor performance. Not even including the cost of having an electrician wire it up. I would really like for these to work well because it is such a good concept. I've considered putting a vacuum hose on the intake and running it into the attic to blow hot air on the cars, but that can only do so much.
