It didn’t work

Easy to apply

This product was extremely easy to apply. Was applied to asphalt roof shingles with small to medium amount of moss. Moss has turned yellow brown indicating it appears to be working as intended. There is a vertical window on the side of the bottle indicating amount of remaining product in the bottle.

Why leak when off

The container leaked as soon as water pressure sent to it in spite of being set on off. Got soapy slippery water on ladder rungs which i didn't appreciate There should be a distance setting so can reach further on a roof, too. Had to apply from a lower roof which means I needed an assistant to let me know if coverage was sufficient. Just applied so cannot describe effectiveness.

It kills Moss

It killed the moss quickly 2-3 days. Where moss and grass were in the same area only the moss was killed not the grass. As far as cleaning the patio I could tell it worked but I was not able to brush the patio for fear of spreading the moss.

Good product, bad spray nozzle

The product works for me. The problem, as mentioned by others, is that the spray nozzle is very poorly designed. The first bottle I bought only dripped, did not spray at all. By now, after many previous complaints, I would have expected the supplier to get it right.

A must buy for Moss ridden yards!!

It definitely works!! We wait a good week for the moss to turn yellow, then rack it off. It peels like a scab. We then reapply to ensure we didn’t miss any spots. Moss is bad in the South especially when the backyard is surrounded by pine trees!!

Still not the best

Moss turns brown after a couple days, but now, 2 weeks after application the moss is starting to turn green again. Awkward to use for spot killing very small areas, so instead I used the applicator to spray it into a bucket and then poured the solution into a pump sprayer. Liquid does give more thorough coverage than the granular product. So far it's a decent job of controlling moss, but not sure of total eradication.

This product worked somewhat. Killed some moss not all.

Not very effective

killed about 30% of the moss

Will be asking for refund

Easy to use but did not work

Works fairly quickly, saw results within 2 days

Worked killed moss

Damaged package

The product was leaking in the plastic packaging. Required immediate complete usage which was not ideal.
