I recently purchased the Metro Air Force Blaster (4HP version) and I am extremely pleased with it. Today, I got caught in several thunderstorms while out riding. In the past, that would have meant that I would have spent most of tonight cleaning the bike to get ready for tomorrow's ride. I don't have to worry about it now. I just have to have an hour or so before I leave tomorrow to completely wash and dry the bike. It even dries the driveway at the same time. I can do a very quick walkaround of the bike to find the very few water spots that are remaining, and I do mean very few. If this Air Shammy is as good as the Metro, then it's a great deal at that price. I paid about $170 at Amazon and another $20+ dollars for wheels for the Metro. Don't expect to really feel the heat. It takes a good 5 minutes or so to warm up and the way you know it's heating is you can feel how warm the hose is getting. My guess is that if they really heated them up alot, you might as well just let your bike dry in the hot sun and deal with the water spots. If you do go with the 4HP Metro unit, get the wheels. It's very much worth it, although the unit is small enough to carry around in one hand while you direct the hose with the other. I had one of those driers that looked like an oversized hairdryer or undersized leaf blower in the past, with no heat, and there is a huge difference in results. When I move the bike into the garage, there are no miscellaneous drips from anywhere...if you did a good job blow drying it the first time. I have not been using a towel along with the dryer, so that may even be a way to speed things up even more. The best part is that my bike looks so great when I actually wash it with soap and water, rather than just wiping it all down with a spray cleaner. I have probably completely washed my bike more times in the past month or two than I would normally do in an entire riding season. It's just so much easier now. One last item is that if you do a really nice wax job on your bike, it makes it even easier to dry without spots. How's that for a glowing review of a product?
