I don't think so. I have always had a Clifford on the RS. It came with a Concept 300, then when it was given a new lease of life I had the top of the range Clifford alarm fitted with lots of add ons and it has never given me a problem in 2 years.

People think Cliffords are shit but if they play up it most likely that the install is shit rather than the product. I will always have a Clifford on my cars purley because of the amount of add ons you can have.
