Seems pretty good to me

I must say, the plugin looks great, it’s highly customizable, and the end design looks excellent too. Only problem is a need a date field and you must pay to get this, and I can’t really justify buying a plugin just for a date field, something that’s quite commonly needed. The reason I come to www.remarpro.com is to find a free solution and without date picker, to me it’s useless.

If you want you could always create a custom text field and ask for the date, but then you don’t get a date picker.
