This product is really good and easy to use.  For people that don't have a lot of spare time its great because you don't have to worry about putting in drier sheets and taking them out all the time.  One thing i also noted is that is leaves lot more smell on your cloths than the sheets do.  I really like this product it actually does what it says it does you just stick it in your drier and forget about it for 4 months you don't have to keep buying sheets and that cuts down on the waste of boxes and trips to the store.  great product i think you could even justify in saying its a green product...
