Component Ace is all that it advertises. It is easy to implement and is very fast.
In addition, the customer support is the best I have ever had. All my questions were answered within hours, often immediately. The responses also answered my questions, no need for followup emails.
If your application needs the functionality that Component Ace provides, search no further.
