Arrived with tops off, product about half gone .

Walmart packaged multivitamins in same box as 2 opened canisters of moss treatment powder. What a mess and now can I be sure vitamins are okay? Common sense, folks!

Bought for Early treatment of moss growth on our property but takes 3-4 weeks to kill it. However the store was clean and staff was friendly thank you for asking but it’s kinda creepy to get a survey sent to my email when my husband bought the item with his credit card

Works pretty well but application is a bit tedious on patios since wind can blow it off and if it rains too soon we aren't sure how effective it was and if we need to reapply. We've used it previously as we haven't found another product that is as effective. Especially good on light roof moss situations

The product works great. I usually apply the product each November. I sprinkle at about a 1 ft wide strip on both sides of the roof ridge line and let the rain do the rest. The product kills any Moss that's on the roof and keeps Moss from growing for the entire winter.

Deceptive labeling! Bought for use on my roof. The front of the package quite clearly reads 3000 sp ft. The fine print on back though, under directions, states 2 methods to use the entire canister over 600 sq ft, no mention of how it's to be dispensed over 3000 sq ft.

The can is half full, horrible.

Bought two cans of Moss Beware at Henry Hardware for $19.99 each and the cans are like half full, what a ripoff, I won’t be buying this product again. I barely had enough to do a rambler rooftop.

I applied the product in several rows across the roof line, two days later it rained and the product was no longer visible. A week later I was working on a roof vent and notice there was significant active moss had started growing al several areas across of the roof in places the the product was applied. Didn't seem to work even though I followed the directions which are limited to "Apply the product across the roof ridge line." Probably won't use this brand again.

I've used this product for years. It has always worked for me. My area has no problem growing moss. Very convenient to use. I sprinkle it right on the ends and make passes about every 10 feet across the roof as well as on the peak. I do this in the early fall before the heavier rains get a chance to flush it off the roof too quickly.

Careful of packaging

Bought this in-store. Many cannisters were leaking the zinc sulfate monohydrate powder. The packages and shelf was covered in it. I warned the checkout person to wash their hands. Have yet to determine product effectiveness on my roof as we are in a drought

Lid falls off!!! Dangerous to family!!

arrived open with half the powder spilled out. made a mess in my house and exposed my family to these chemicals. surprised delivery company like FedEx or USPS tolerates this. TERRIBLE PACKAGING!!!

Ground too fine

Even the slightest of breeze has this toxic substance dust going down your lungs. The packaging so cheap, top popped off and dumped large clumps all over my roof.

I place this powder on the peak of my roof, on the ridges and halfway down each section of roofing and the combination keeps my roof moss free and has done so for five years, not a spot of moss. You have to be vigilant about doing it every six months. The best times are early winter before the rains, just before a rain forecast and then in the spring again before a week of rain.

The best roof saver product ever. After two decades my roof looks still in great shape. Getting a new roof is expensive. Preserve your roof life with this product

Deceptive Labeling

OK, so I read on the front label that this covers up to 3000 sq ft; so I buy it. When I get it home and read the directions for use, it directs the user to "apply 3 lbs. to 600 sq.ft. of treatment area". The 3000 sq ft coverage only comes into play for "prevention only". This stuff does NOT kill moss at the 3000 sq ft rate as one is lead to believe by reading the front label...a little deceptive!

Great product

This product kills the moss that bead up, even heavy beads, on the shingles. Kills it quickly then come back even weeks or months later with a leaf blower or a wide push broom. I just removed tens of lbs of moss beading that I lazily didn't remove last year after applying this product last fall. The only difference was this year I wasn't on.my knees, sitting on a cold roof scrapping off moss beading with a paint scrapped or my fingers. This time?? A leaf blower removed most of the dead moss material. However, I used 2 Cans today, and I need to get back up there and apply another can along the ridge after using a leaf blower, or a broom. With shingle roofs?? The most gentle application an removal is best as to not remove asphalt shingle material.

Gets rid of moss quick and easy

Corry's Moss B Ware is a must have for anyone dealing with moss on their roofs or sidewalks. Living in the PNW, moss grows on my roof every year. The green moss is an eye sore and bad for the life of my roof. With Corry's, I can just sprinkle a can of it on, leave it and have the rain dilute it. Within a few days, I saw results. Super easy to use and you get a lot of coverage (3,000 sq feet) with a single can. Great price for the product compared to other brands I've used. This review was collected as part of a promotion, and the opinions are my own.

Works great, harmful to fish and plants

Moss B Gone is a powder that is easy to apply and works well both for keeping moss off and removing existing moss from the roof. This product is toxic to fish and plants, so should be kept away from streams, flower beds, etc. That said, it's hard to do since rain will wash it into waterways (eventually) and plants. I'm hoping they will come up with a more environmentally friendly version.

It works...

It works as advertised. Not as rapid as some more caustic stuff but it did wonders on my patio and steps that seem to always collect moss. The square footage is misleading. I used two containers to do my roof. Looks like I may need two more.

The product was delivered to my residence without any issues. Upon using the product it was found that the powder had compacted (or been exposed to damp conditions) to a near solid, requiring significant agitation to break up the powder enough to be used. I was not thrilled with having to take this step and still had many clumping issues in the product that I spread requiring more of the product to be used than in previous years. Overall buying this online did not provide me with as satisfactory of an experience as purchasing in stores as I have never had this issue with containers bought in stores.
