As with most of Griot's products, this item is overpriced compared to its real-world performance. I was really excited for this product and ordered it before any major reviews were out. I wish I had waited. It's clear I'm not the only one who is disappointed in this. The canon simply does not foam as well as cannons from other brands, most notably from Chemical Guys. I saw Griot's has responded to some of these complaints and says it's because customers aren't using their proprietary soaps. That's ridiculous. But even if you believe that, Griot's own videos show the same level of foam that I'm getting with their cannon using Gtechniq's W4 Citrus Foam. So even if I were to buy their overpriced soap, I wouldn't be getting more foam. Chemical Guys' foam cannon is just miles better than the Griot's cannon when it comes to foam. The only thing the Griot's does that the CG cannon doesn't has the ability to screw on 16 and 32oz bottles directly onto it and have the metering tip. That's why I got the Griot's cannon, but my foam game is worse because of it.
