I cautiously say "yes" to buying this product again, because of the price obviously. It's one of several products we use on stains and it's certainly the last one of the group we try. Not sure if that gives an ideal example of what kind of stains the Pro Fiber Rinse & Tannin is best at removing. But, when I've tried it on stubborn stains, ones that my other products have not been able to remove, it has done very well. So in the end, it's nice to have it on hand for that unusual stain, but I'm not going to use it on a regular basis. It's just too pricey!
