2 dollar shop, page-3

Not a downramp but the exact opposite!

The spinning wheel (which spins when you inhale) can be interchangeable. This meaning that the kids don't get bored looking at the same thing over and over again as they can change the wheel from lets say a transformer to the incredible hulk (one side Eric Banner the other the hulk). The product it self as you say is around $49 (don't know the exact price). But if they market the spinning wheel at the right price then kaboom! Sales of the inhaler and the wheels will go through the roof.

The whole point of the inhaler is to get kids to take their asthma regularly and to help the delivery of the drug. And by making this process fun help in their recovery as they get the right amount of drug at the right times.
