I've ordered a few things from them over the past year or so. The big thing was my show helmet during the helmet awareness day sale last year. Most recent order was for a pair of breeches and portable water containers (since I couldn't find them locally). They were awesome in letting me know promptly that there was an extra shipping charge on them even though the website did not say that. Since I needed them, I authorized the extra shipping and had my order in less than a week!
I also love Adams. Their store is worth going to if you are in southern Maine. They have the little stuff you didn't know you needed until it stared you in the face. I've gotten great end-of-season buys on Irideon Windpro breeches and a Pessoa rain sheet, all shipped to the house at no charge.
