Product review (1 stars): Lasted 11 months and then quit.
I bought this mid September of 2017.  It quit working after less than 11 months.  It seemed like it started drying less and less over the past few months and then as of about 2 weeks ago, it quit completely.  As with other non-amazon sellers, it is almost impossible to find warranty information.

Tried to contact seller, but have heard nothing back in about five days.
