I was so excited to try these reasonably priced, green fabric softener sheets, hoping they would compare to my favorite Arm and Hammer Vanilla Lavender 2 in 1 Dryer Cloth sheets...there is no comparison. These sheets were oddly perforated, didn't noticeably soften clothes, didn't leave even a faint scent; I think they may have helped a little with static cling, but I'm not even sure they do that. The packaging also looked so much like they should have been lavender scented that I assumed they were and didn't read or see otherwise on the package. I continued using these even after not liking them, and was so very glad when I was done with the box of them. They may be hypoallergenic, non-toxic, etc. but if they're not effective- and don't soften laundry, then it really doesn't matter how "green" or safe they are, at least in my opinion. You can definitely only use them once and they are small in size. Don't buy these and waste your money like I did.
