Looking for feedback on Raritan's Knock Out Odors (KO2) kit

Good morning - I like the idea behind the Raritan KO2 kit: with every flush a little bit of C.P. is pushed through the pump (I've a SuperFlush) and through the bowl to prohibit low tide-like odors. It's on the pricey side, but includes a metering valve that appears to be expensive to buy on its own so is probably not a horrible deal. Oddly, while lots of stores stock the product I can find few comments about the product in the forums. Does anyone here have good or bad things to say about it? Thanks!
I ended up installing the KO2. I like it a great deal and recommend it.

I had one issue with the install. Item #4 in the pix below is a T check valve that sucks in the CP contained in the KO2 tank (item 1). The fitting where the CP comes in from the tank and the fitting on the downstream end of the T both screw into the body of the check valve and both of them leaked. I unscrewed them and gooped up the threads with thread sealant paste and all was well. I recommend that anyone who installs the KO2 does same before putting everything together.
