I have a few Wonderoos and am looking to buy some more, but am a bit confused by V1, V2 and V3. I understand there are some with PUL outer and some with minke outer. Some have a 1-button double insert (small insert and big insert clip together with a popper) and others have a 2-button double insert. These are made of micro-fibre. I also have one with a 2-button hemp insert with red stitching - it gets a bit crunchy in our hard water here. Are these V1 (one popper) and V2 (2 poppers)?
Then there's the v3 which I haven't seen - is it an hourglass insert with a foldable insert clipped on top?
Grateful for advice. Thanks.
