I have it and love it. But you may not be able to get it anymore unless you want the model for a plug-in Prius. Norm (the inventor and seller) announced in May that he would discontinue the basic model when current inventory was depleted. A post on his web
site in late June said there were still some available. In a more recent check I didn't see it listed anymore. You might e-mail him to see if he has any left if you're interested.
