Yup I got it from Amazon cost $180, I have a clone earlier but that thing fail and I return it. This v4 have a lot of parts and the cloner still can clone it BUT once the clone messed up with a little dimension and stuff espcially the spring your
tank gonna have some problems, that's why
svoemesto came up with many parts just to slack those cloner out there IMO, if you're lucky you might get a perfect clone. Because of those complicated engineered build I'll go for an authentic one, been using it for couple of weeks now without any issue at all, but it's your choice to choose either one, hope this info help you and others out there to decide.
