Excellent product but the shipper needs to better package the bottle with the hose nozzle. It came in a sealed plastic bag inside the shipping box, and the plastic bag has a lot of the liquid in the bag because the nozzle gets banged around in the box and it leaked into the bag. But otherwise, good product.

I've used Wet and Forget for pump for years and love it. We wanted the hose connection Extreme for the hose connection. This is more concentrated than the wet and forget that you mix 1:5 and the hose makes large and hard to reach areas easier.

The main positive is:

1. You can do large area with fan nozzle and far distance with other nozzle.
2. Like that you see foam when on (this confirms that it's on).
3. Like that you can turn on water without product.
4. Like that it didn't leak around hose connector

The main negatives:

5. It didn't cover 2000 sq feet. I contacted company and they said coverage is only 750-1000 square feet if you are using on a porous surface. We used on bluestone and vinyl siding. Although Bluestone is porous, we didn't spray extra due to fast absorption. Our overall coverage was close to 1000-1200 sf.

6. Spray and distance nozzle kept coming off. By the time I was able to turn off sprayer and put nozzle back on, product was misdirected and wasted.

7. Difficult to turn off for nozzle or location change. While struggling you are misdirecting and wasting product. Note: I have used other products with hose spray applicator that made on and off easy. I sent a photo of one to the manufacturer.

I'm hoping company can make improvements to the applicator. While description states up to 2000 sf, product should indicate coverage will be 750-1000 sf when used on a porous surface (e.g.,brick, driveway, roof, paver, etc). I'm also hoping that I will get the same good result over time as I normally get with the regular Wet and Forget. Since results not immediate, time will tell.

Fortunately I ordered 2 bottles. One leaked really bad; half the product was in the plastic bag. Amazon accepts no responsibility! Wet It is shipping a replacement. I had no problem with the sprayer, but I couldn't get 30 feet out of it; probably 15. I did watch a utube video that suggested using a shut off on the end of the hose with quick connect attachments and that worked really well. I have to see how well it works in time, but I'm hopeful. Not happy with Amazon!

Second day, got better range out of the sprayer. Seems like it works better when it isn't full,
Got really good range with the stream noodle versus fan

Takes one or two rainfalls for the product to begin to work its way into the mold. After that you might see results for several months.

The attachment to the garden hose needs a ballcock so you can shut off the flow as you move to your work area and return to the spigot.

The twist control should be removed entirely so that the mixed product always flows when the ballcock is open.

See new notes! Initial problem resolved - good customer service.

The applicator indeed is terrible. Broke with the first try at application. Luckily, I started with a spray of water to see what the pressure and reach would be, because I got soaked. At least it was without giving me a chemical bath. I have a call in to the manufacturer, so we will see how this gets resolved. And then I will update on functionality and results.

Edit: They expedited a new nozzle to me and it worked as it should. I sprayed the side of house that has moss quite easily. The spray reached the peak of my 2 story house and then some. The moss was quite heavy in some spots and fairly widespread over the entire side. I used quite a bit of product. It was lighter the next day and turned to light tan the 3rd day and is now almost gone. Good job!
