Scott has been very helpful and informative on guiding me through the purchasing and installation of my terminator X max system.

Super helpful and knowledgeable. Full product line and accessories at excellent pricing.

The Ordering process was so easy and non-painful. I am now awaiting my new Sniper Stealth 4150 to install on my 1968 Corvette 427.
