Might seem like a stupid question. However, I see some products on the site that say they are Vision products, and others that just say the model name of a Vision product. An example of the later is the Vivi Nova and Vivi Mini Nova. However, I don't find Health Cabin listed on Vision's website as an authorized vendor, and they are selling a V3 Nova. My understanding is that the latest version is actually 2.5 and no real V3 exists. Thanks in advance for clearing this up for me.
