I've purchased 20+ isolators and bi-directional relays over the past 5 years for our fleet at University Laundry. These units have performed extremely well in various climates across the country. I really like how easy the units are to install. Once it's installed they don't require any maintenance or monitoring. We've been using the first isolators we purchased for 5 years and they are still running strong. Many of these units are mounted to the frames of our trucks and exposed to the elements. What is even better than the products is the customer support. Seriously, when the company owner replies to calls and emails, many times within minutes, I couldn't ask for more as far as customer support. I've recommended Perfect Switch to weekend adventurer trying to maintain batteries for camping and winching to the over the road driver powering everything on his rig 365 days a year.
