I bought one of these about 3 yrs ago and have used it about ten times. Went to use it about 2 months ago and the screen wouldn't light up and dispenser tube would just spin erratically. Contacted them and with 0 hassle they sent me a new one. So kudos for that. My question is would there be some kind of factory reset a person could perform to get it back working or just chuck it? Anyone have any knowledge on this? Just wondering
