Anyone familiar with RN/LPN Refresher Courses by Kane Educational Seminars?

Has anyone heard of / attended the RN/LPN refresher courses by Kane Educational Seminars (www.nurserefresher.com)? They hold 1 day (6 hour) refresher programs in which nurses who want to re-enter the field can brush up on their clinical skills. They are based out of Florida but travel to other states and the 1 day course costs approximately $250. Would this course be a good one to take? Is this legitimate? Or are there better refresher courses out there, maybe ones that are longer and include both hands-on and book-type reviews? Thank you ahead of time!
