I saw these and then read some reviews. Rolled the dice and took a chance. Glad I did. These are a very effective softner. Not sure if they speed up the drying time, but the laundry was softer.
When I saw the price $109 with free shipping. I jumped and jumped fast. Other sites have this exact same set up for $140-$160 plus shipping.
If you want or need one. Do it.
