I've just got mine and I'm really pleased with it! The box is massive (I can see why they didn't include a washbag - it would have had to be enormous!) and there are plenty of full sized products I will use.
I needed some more Vit C anyway, and for what I paid (£100 including BD credit and loyalty vouchers) that is what the Zelens is worth, so I'm seeing everything else as a bonus!
