San Jamar Tear-N-Dry Essence Paper Towel Dispenser Automatic Dispenser, for 8 Inch Rolls, Dispense in 10 Inch Portions, Plastic, 10 x 14.75 x 12.25 Inches, Black

I bought 2 of them, only couple months same problem both of them, paper not come out automatically... I changed new battery but same problem... I thought the sensor not working good... My recommend is "DO NOT BUY IT". Looking for the others product..Amazon should refund all money back to customer... or exchange the new one... this product is "s...k"
