Seems to work, but slowly...

Using this on fireplace front on bricks with smooth and rough spots. Works best on the smooth parts of the brick, but takes a lot of effort and time. Still the results aren't that good. Good thing it wasn't expensive. Not sure I'd buy again.

I've had this for a few weeks now and am not noticing much difference in my water.  Will give it a couple more weeks.  I bought a new shower head and that seemed to make this filter work better (my older shower head was OLD).  But I'm not noticing a difference in softer water or better feeling hair or skin......yet, anyway.

This product works as described, but it takes a very long time to see results.  I will keep using it.

After 3 weeks of use- haven't noticed much of a difference, except perhaps less smelly farts than usual. Switched from fortiflora to this on a whim  (fortiflora was backordered). She doesn't mind the taste, the price is very reasonable, the ingredient list is impressive. As far as any skin benefit... her dandruff has increased actually. And her recurrent pawpad infection has flared up (probably just a coincidence though). I guess this product gets 3 stars because while it hasn't helped, it hasn't really hurt.

Works, but takes a few ears to get the knack of using it.

Seems to calm my kitty - not quite sure, but I think so.

This seems to work somewhat... I'm only concern is the spray runs out fast so if you aren't watching, it's not much of a training tool.

Happy with it when it is working, but seems to gradually slow down over a few days. After 2-4 days will have to reset it because it has slowed down so much. Resetting seems to fix it but this gets annoying after a week or so. Not sure why this happens.

We have been using this for just over 2 weeks & I can not yet see a difference in the amount of barking in the house.  The guidelines that came with it said that within a month, one should be able to see a decrease in the amount of barking that goes on in the house.  I am not giving up on it & am still hoping to see a positive benefit over the long run.

Takes some time to get used to, but does work.  I have since discovered Dri-Clor - which has stopped my sweating problem altogether.
