I had an opportunity to receive a free sample of this from Vocal Point before it hit stores.  The thing that I like about the Bounce Dryer Bar is the fact that I can leave it in the dryer and I don't have to constantly change dryer sheets.  With having to quickly change out loads of laundry, not having to take out the dryer sheet is a nice feature.

The bar easily attaches to the inside of the dryer.  The downside is that if it does come loose then the dryer bar can bang around and break up in the dryer.  I had a few small pieces come off mine, but fortunately it wasn't a lot and didn't stick...
