I had purchased the Sansula Basic on the recommendation of Laura Inserra - sound alchemist. I loved the tone and used it regularly in my classes. I purchased the padded case and all was well until it slipped out of my hand onto my yoga mat and to my dismay the membrane exploded into many pieces - I was both shocked and very disappointed.
I called the company right away and the owner explained I would have been better choosing the more robust version as I was transporting it regularly and that the basic model is much more delicate and is more suitable for studio work. As repairing mine would involve costly shipping back and forth to Germany, she recommended I purchase the Renaissance model at the repair program discounted price, which I did.
So lesson learned, buy the more robust models if you plan to use the Sansula in classes or for travel. Thank you We Play Well Together.
