Version ones are clearance stock for most retailers - Vapourhut are neither advertising these as Vivi Novas nor Vision products nor version I Vivi Novas. They could be selling any old toot (not that I am in any way saying their products are old toot) or clone copies; Vivion Vivi Novas are an established product from a specific manufacturers where users can have a quality expectation. And with the exception of old stock version I's on sale/special offer clearance, I haven't seen the larger ones on sale for less than £9.50.
