My T-62 is 4 years old, has about 300 hours on it. I like everything about it EXCEPT!!! The self program mode has never worked from day one. With only 300 hours on it the motor control board is over heating and will soon burn up. Horizon took two days getting back to me and could not provide the part I need but did refer me to another company. For nearly $2000.00 I expect any product to last much longer than this.
