Works great.

For the record I have not yet used the Aquabrick Purification System. I will however, tell you that the quality is well built!! The container is made of solid and thick plastic. The cap threads on very easy and all the tube connections click together with no issues. I choose this over the Waterbrick do to the the fact that this one is easier to clean out, there are two molded handles not a wire handle. Also, the spout on the Aquabrick is at an angle, making it easier to pour all the water out. I will definitely be buying another one!!!!

While I inspected the contents of the box, I do not plan on actually using the product unless there is a dire emergency. My rating is based upon what others have said after they used the product.

All I can say is this is awesome

Unlike one review in particular that I read, mine do NOT leak. I inspected all six, verifying each lid had a gasket and each mouth rim was smooth. Satisfied, I washed and rinsed all of them thoroughly, then filled each fully with water, with only a small air pocket at the top. I carefully placed each lid on, making certain they were started correctly and tightened easily. I placed them in a stacked-cube type interlocking arrangement, each laying horizontally and performed a 48 hour leak check on a tile floor. ZERO LEAKS. Not even a drip ANYWHERE. If I need more, I'll certainly buy more of this brand and the size is easily handled, which was the attractive part of them for me for moving and portability in a time of need. I have initially rated at Four Stars, due to the fact that I have just started using them. I fully expect they will be a 5-Star purchase as time proves their worth.
