Nanostick

Has anyone used or have any info on the Nanostick?   A friend swears by it but I can't find much about it.   Thanks

I have seen these pop up every now and then for the past 10 years. If they work as claimed I do not think it will do much in a spa, it needs light. How long is the cover off on your spa?

Only the 20 mins at night I am in it 3 nights/week.  How does it work...I can't seem to find much on it
