After about a year of using the monitor the volume control wheel has problems. As you turn it or sometimes when it is sitting on the table the volume will cut in and out like there is a short circuit in the volume knob. The first one, after about 9 months, we returned to Summer and they replaced it with no problem. The second one is doing the same thing so we are going to try to replace it. However I think we've had it just over a year so I don't know if they will.Other than that is it a great product.
