Arm & Hammer Odor Busterz Balls (6-Pack)

EDIT #2: I wrote my previous edit a over a month ago, and I am once again upping my rating, this time to the full five stars. After using the first ball in my laundry closet for 60 days I replaced it, but just out of curiosity I placed the "expired" ball in a small drawer where I keep my dog's harness. I wanted to see how well it would work, and I was surprised to find that it continued masking odors for another month before I finally noticed the effect wearing off. So while A&H says to replace these every 2 months, it seems that you can safely bump it up to 3 and still get good results. That really increases the value of these things, and overall I'm just really impressed with this product. I would definitely say that these are on the same high level as other A&H products, and up to 9 months of odor elimination for $6 is a steal in my opinion. Definitely glad I stuck with these, and I can now highly recommend them. EDIT: I'm upping my rating from three stars to four. I still think that these could be stronger, and I generally expect more from A&H products. But I originally wrote this review a few weeks ago, and I've had one of these balls sitting inside of my laundry closet the entire time. It's a small closet, but it houses my dirty laundry hamper so it always smells pretty funky in there. To my surprise, I've noticed that the entirety of the closet now smells noticeably better and cleaner than it ever has before. One odor ball does a good job of masking the dirty/sweaty smells, not just near the hamper, but throughout the entire closet as well, even the very top. It doesn't neutralize the bad odors entirely or anything, but it is doing a better job than I initially gave it credit for, and I would much rather have these than not. ORIGINAL REVIEW: These do work, but I just wish they were better. Maybe my expectations were too high, since I'm a fan of A&H products. But I thought these would eliminate odor more than they actually do. They work best in really small/confined spaces (cabinets/gym bags/laundry hampers/etc) but even then, the odor elimination isn't as powerful as I hoped it would be. The bad odors still remain, though they are definitely subdued. These barely do anything in larger spaces though (closets/etc) which is very disappointing. I don't expect miracles but I did expect them to help a *little* in an extremely small apartment closet, which they don't. The balls themselves have a strong, chemical-y scent, which I personally like, but it definitely made me grimace when I first smelled it up close. But if anything, I guess I wish they were even stronger - maybe then they would do a better job of truly eliminating odors. I think these are still fine and worth the price (each ball is $2 and lasts for 2 months which is a pretty solid value) but don't expect to use them for anything larger than a duffel bag.
