Review on Zerostart 310 0054 Engine Block Heater by Chris Cruz

I have used zero start heaters on my units for many years. All have worked well. This one seems to be of the same quality. I gave 4 stars instead of 5 because I haven't used it yet. It's +90 degrees Fahrenheit daily this time of year, so I haven't plugged it in yet. I trust this brand so I'm not worried it will work when it gets cold.
