  1. I am definitely interested in cutting my drying time. I do dry on a rack, but with a family of 4 it's just too hard to keep up.With two kids in cloth diapers, I have a hard time getting them on the clothesline every day! For the odd time I put them in the dryer but it's still takes me a lot of time until I bought the best dryer ever. It's so hard to know these days what is worth spending our ever-reducing disposable income on, so if someone is curious may check this guys -

  2. Thanks for sharing this thorough guide for operation and how to clean your rotary dryer.
