The only model that comes with the center mount plate is the PRO version. This is because in order to attach the plate we have to drill and tap the rails for the plate to screw into. The base model and the carbon version are hollow so they can't be drilled and tapped.
We don't accept returns from Kickstarter projects so please make sure if you become a backeryou intent to use and keep the unit. Thanks for your understanding. We will however repair defective units at no cost to you if that is the case.
Customs fees vary depending on the country you are in so we would recommend checking with your customs office before you become a backer. The full amount of your pledge will be reflected on the invoice in your package, however it will be marked as a "gift" since your reward is a gift in return for your generous support.
