We replaced a bunch of WordPress submission forms across a ton of clients sites with Deftform, we had noticed that the original WordPress forms (with file uploads) seemed to be causing some strain on that specific shared hosting account. With the ability to have unlimited storage, everything works great and you can pretty much customize the forms to match your website exactly down to fonts and color schemes.

They also have had frequent updates as shown in the change-log since purchasing, and the new ability to track partial submissions seems really cool as well. All in all for the price and the features provided we feel that we got a great deal on AppSumo.
