Some programing lost when batteries replaced. Low RF strength. I had to retire mine when the transmitter started sending uncommanded random IR signals, frequently changing the cable channel while recording. The reviewer has used this product for 1-3 months. Setup not difficult.
Instructions are clear.
Has great potential. Uncomfortable placement of VCR controls. Reading the features on this one made it my choice. Unfortunately, you cannot test out or trust the information they provide about the distance the RF transmits. The house I live in is essential old and wooden.
