I love how easy it was to install, deploy & use with ColdFusion 10! It looks really professional (even though its free) which helps our clients feel more comfortable about using us as their development partner / solution provider/ consultant etc.. There isn't much that we dont like either - maybe some of your other customers might think otherwise but they probably havent used this product yet ;) The pricing structure could be better in my opinion too- perhaps add an additional tier or charge slightly higher than what you do now? We've been able solve all sorts problems relating specifically around security related issues within ecommerce websites developed by ourselves through coldfusetoolkit such things are hard when working alone without any assistance from others :).
