Query: Stops working every two days!!

I have had to replace the batteries several times on this unit and I've only had it for a few months. Last week I just replaced them again with brand new Energizer Max batteries ([...]), and they lasted two days. Yes, I said two days!! Who can afford [...] bucks every two days to maintain a [...] dollar unit? I think I'll have to live with a little stink, 'cause the cost stinks alot worse. Thanks for flushing my money down the toilet, The First Years!
