So I got the "2fer" deal, ordered right before I left on vacation. They arrived while I was gone. What a waste of money. Total false advertising. The advertising says to fill it and it’s good for 8 hours, but it's more like 20 minutes. I would have rated this product a zero, but it was not an option.
I had missed the 60-day return date, so they will be donated to the Goodwill instead.
Bottom Line: No, I would not recommend this to a friend
