Re: msd knock alert

I have one of those knock alerts. It works good, the only problem I had with it was the buzzer is a high pitched noise and my ears are bad. Thats why I bought the damn thing in the first place-cause I couldn't hear the pinging. It has lights that show the knock as well. If you are interested I might be interested in selling it.
