Nooby here, but I use it on my FS M&P, applied once per instructions to initially treat (borrow hair dryer with permission from Mrs., strip, heat parts one by one, apply paste with toothbrush, let sit for a couple minute, wipe clean, reassemble).
I opted not to use the solvent, just started with paste and the CLP.
So far seems ok, pistol (and me) both pretty new, so my experience base is near zero. I would not dream of commenting on other products; ya'll have forgotten more about firearms than I'll ever know.
I like the fact it was developed by a serviceman (SEAL I think) in the USA, is non-toxic, smells ok, appears very effective for cleaning / lubricating / protecting, doesn't leave any residue, leaves a nice non-shiny matte finish, is safe on plastic and metal, does not require gloves, is non oily/greasy, and does not seem to attract dirt. Lastly, it may be me, but it does feel like when I clean after a range session, there is not much accumulated powder. I run a boresnake through the barrel then a couple wet/dry patches, plus a general wipe out of the slide etc. That is about it.
One suggestion: buy as small a size (in oz) as possible; I think if I could have gotten a gun show sample (1 oz?) that would be fine for a hand gun. I have a 4 oz bottle of CLP AND a tub of paste, and I've got plenty. As some have noted, the stuff is not cheap.
If there is anyone in the Tampa area wants to try some (free) I'm either at Shooter's World or Bill Jackson's Outdoor World. Shoot me a PM, be happy to let you borrow/have a teaspoon of each in a couple lunch baggies.
My 0.02.
