Great product, bad documentation.
The FL is great, the documentation considerably less so. Mine did not come with any instructions at all. When I found that the only instructions the FL itself came with were printed on the side of the box (and were not very detailed) I went online to look up the proper care procedures. It's a good thing that I did, if I hadn't I very likely would have used soap the first time I had to clean it, which is a no-no.
Luckily, the add-ons I purchased with my FL did include the instructions, though why the instructions were inside the packaging of the stand alone products I purchased and not in the box of the FL itself is a mystery. The instructions are carefully disguised as a promotional cross-sell pamphlet for their other products. If you completely unfold the cross-sell, you will find, hidden within it, the instructions for use and care. If you only partially unfold the pamphlet, as I had when I first came across it, there's a good chance you will miss the instructions. Had I purchased the FL alone I wouldn't have had them, and that's kind of distressing as there is important information in those instructions. No harm done, but there easily could have been.
