That's usually the case. They go in thinking it's some kind of cool CAVE thing and then next thing you know they're "Fragged"

I did get 2 of the #2's. They work great. I have mine on a wavemaker. You all have given me yet another thing to be concerned about. It came with a screen to put in when using the directional attachment. I guess I could glue that on the front of the base unit to protect the innocent. Any thought on that option?

the screen (directional flow adapter,concentrator) is the reason why I started this thread ..

I did not get mine but I have heard mixed opinions on them,to use them or not.
right now I have great flow without them on,but they are sending me 2 in the mail and will try them out to see if it makes a difference..
