I really have no complaints about this product. It comes from Revain in a box that appears to have been shipped by Revain from APEC. All filters were hygienically wrapped in plastic wrap (and let me tell you I'm picky. I look for EVERY problem). I didn't notice any cracks in the plastic. One of the components is external, so not packaged. You just attach it. I also order rings, also without problems. We let water flow through it for a long time after the first change. I don't know, maybe thirty minutes? It has a little flavor the first day, so I usually pour it out and drink other liquids. You will only notice many air bubbles after the change on the first day. After that as usual. I am grateful for this easy way to order from Revain. I hope this review helps someone.
