I have one but have never used it. Do have a katadyn water filter that works extremely well. Plus a few bottles of water purifier (iodine crystals) for the mobile side of things. Also, have the calcium hypochlorite and a Berky water filter.
I have the Berkey and the calcium hypochlorite but other than stored water,I don’t have what you do. I ordered some Seychelle water bottles for $16.50 from the LDS store. They filter 100 gallons per bottle. Replacement filters there are only $9.00. They looked like dandy prices to me. They were quick and didn’t charge taxes or shipping.
