I don't have a lot of first hand experience with Adam's products; I have tried a few of them a couple times.
However, they appear to have a loyal customer base who not only appreciate their product offering, but also their customer service. Working for a company (PBMG) that focuses on customer service, I can admire their dedication. It is nice to know that the detailing industry, as a whole, has so many great companies that have such a great customer service reputation.
I am sure, based on other's testimony, that their products perform well. Ultimately technique will always trump product selection. SSizzlin has bought, tried, and returned more products from more companies then a public library and has had some really positive things to say about Adam's products. Ultimately I am biased, but I am sure @ Autopia, because of wide selection of premium brand products, we offer anything you could ever what at any price range you are looking for.
