This is a good product. It would be perfect if it did not contain propylene (sp?) glycol. It is the only product I use which contains it because I see no benefit in using cosmetics or dental products containing certain chemicals and any form of paraben on a daily basis. If I find a product w/o proplylene glycol that does a great job, I will switch to it.

I have used the Shark Steam cleaner before. While I liked how well it seemed to clean it had to be pumped, and it left streaks on the floor. The Hann is much more versatile and works better than expected. Unlike the shark or ANY OTHER steam floor cleaner the HAAN will sanitize floors in one second. Other brands take fifteen seconds. That was the initial reason I went with the HAAN. We have dark hardwood floors that show every little scuff and fleck of dirt. With the HANN steamer I am able to quickly clean the floors. It leaves them feeling clean with absolutely no residue. It is very easy to refill. I am able to clean my floors for roughly twenty minutes before I need to add more water. I definitely recommend buying extra pads. You will need them. For the manufacturer I purchased brown pads that are thicker and pickup more dirt.

I got my Trace Sport at Performance Bikes with a white/red/black color scheme (it was a special edition I think). I actually didn't know how to ride a bike before I got this one (go ahead, laugh) but don't be fooled, I've tested other bikes after this one but this is a great bike for the price and I'm really happy with it. It has all the speed of a road bike with the ruggedness (and heft) of a mountain bike. The fastest gear is super-fast and if you're in city traffic you'll find yourself pulling out in front of the car next to you from a dead stop. Along with the fast, smooth drivetrain comes a pair of cabled disc brakes which are extremely useful among Pittsburgh's many hills. Don't touch the rotors after a long, steep descent though. It's a very confident ride especially where potholes are common; this bike handles all sorts of hazards like a champ. It's pretty light as well for everyday commuting but it can't beat a road bike in that department. My only qualm is that the frame is pretty wide to make space for the brakes and since disc brakes still aren't terribly common, you're going to need to spec order some parts (rear racks for instance). Even so, this bike has great value written all over it.

I didn't notice a difference with the first two uses, but then, by the third use, I really saw whiter teeth. I use every other day. Every day with sensitive teeth did hurt a bit. Also use remineralizer.
