Instruct: Classify Amazon reviews into positive or negative sentiment
Query: VERY undependable

Have had this for a couple of years and it has not worked more than two or three times. Have had the retailer come back and "fix" it but only works for a day or so and then quits again. If you have a need for an antenna rotor, THIS IS NOT THE ONE TO BUY. A total waste of money and will not operate properly.
