Amazon's Prime Try Before You Buy - Experiences and Impact on Return Fees?

I got invited by amazon to “prime try before you buy” program. previously it was “amazon wardrobe”. Anyone has experience about this program? I sell clothing and in our category returns are really high. The good thing about this program is if customer buys and returns in one week I dont pay any fba fees at all. So in that case my return fees may reduce if customers return in one week. But the bad side is people will likely buy my product because they dont pay in one week period which will increase sales but at the same time my returns will increase as well.

So what I am asking is in overall will this program decrease my return fees?

thank you

Only negative experiences from what I have seen on FB. If you can afford getting back used items, then go for it.
