I use this all the time, they just make me feel so good. work on some and not for others.start with one box . there not to big but I always two or three to get coverage fornt , back and top of shoulder. neck and lower back. works for me.

We use this product every single month. Our septic system is over eleven years old. I love the subscription feature because I could never remember to pick it up while we were out. I had to make a special trip to get it most of the time. With the subscribe service, it arrives automatically and I swear it is cheaper than the retail stores.

I bought this top so I could load up the bed to travel 700 miles to mid state Florida in the summer. I expected rain at some point during the trip and it happened. We went through a few dense rain showers on the way there but when we unpacked all the luggage and boxes it was dry in the truck bed. Installation and removal is simple. The only reason I did not give it 5 stars was the attaching hardware was difficult to get into position for an F150. there seem to be a little binding in the channel the latch travels in.

I put this product in and just let it circulate. 72 hours later I still had a leak in my hot tub. So, I put another 1/3 of bottle in, circulated for 24 hours and then drained the tub and let sit for 72 hours. I then refilled the tub and the water level is staying constant. I was losing 2 inches per week. I would recommend this product and use again. Thanks
