The filter itself works great. I could feel the difference in my hair and skin after the 1st use.  Although the return water into the shower wand was ridiculously slow on the output.  I took off your wand and put my shower head back on which was definitely better but still slow.  I have very thick hair and it takes forever to get the shampoo and conditioner out. I realize it's probably due to the water running through your filter but there has got to a faster way.
