    • Looks good.
Looks like a quality item but, like a parachute, you never know how good a safety device really is until you need to use it. Instructions were clear and simple. Final install is solid with the parts they give you.

    • Works as intended
Works great! However, it does not reset when you turn the lights on or mash the brake. Have to physically reset it by removing the ground wire and reconnecting. Still saves the battery so, can’t complain too much!

    • Works, but POORLY designed
First of all, this electric shut off device worked, but it was poorly designed. On the top of the unit is a metal contact to screw a battery post to. But when I used my fingers to tighten it the post kept turning. I tried to unscrew the battery post but it kept turning and it wouldn't come off. I ended up using a large screw driver to lift the top metal contact up until I could pry it all the way up. Then I discovered the problem. Below the metal contact plate was a hex nut that wasn't attached to anything. It wasn't welded to the metal plate. It was merely glued down with what looked like epoxy. It is a horrible design and I'm sure everyone who buys this device will eventually fall victim to this serious design flaw, especially if they try to remove it. I imagine it would have taken another few cents to weld the metal nut to the metal contact plate so the company choose saving a few cents over making the product competently. I ended up leaving the metal contact pried at a 90° angle so I could tighten the battery post to it. I had to leave it in this position because I couldn't tighten the post without using a wrench to hold the hex nut. I wrote the company and even sent them photos with ways to properly engineer this device but I never heard from them. Since I was forced to pry their PriorityStart open I'm sure the company would use this as an excuse to void my warranty, which doesn't last long anyway. And speaking of 'warranties' the buyer has to pay for the return of the unit and THEN the company determines if the unit is bad and from the wording of their warranty information it leads me to believe they will use any reason to avoid honoring their warranty. Obviously their product is poorly engineered when finger tightening a battery post to it will cause an epoxy-held hex nut to break free. The company obviously doesn't care if customers have to be subjected to what I had to endure. Per their warranty it's obvious they wouldn't replace a unit if the top metal plate had to be pried open just to remove their device from a car even though 100% of the problem was their fault. Fortunately, their product does work and I can start my car but to have engineered it the way they did reveals a company that doesn't have a quality control department or doesn't care about what happens after a sale is made. After all, their warranty would discourage (intentionally?) almost anyone who tries to get a replacement or a refund. Lastly, I'm a NASA engineer and no device at NASA would have been made as defective as this device is. I give it 2 stars because it does work but if it was designed properly I would have given it 5 stars. Btw: Any smart and ethical company would take my suggestions and redesign their product and reward a person like myself who told them how to redesign it. It would lead to more sales and more satisfied customers. You'd think a company would have that as their number one priority but sadly most companies don't give a damn about customer satisfaction and only care about making a quick buck. If this company redesigns their product using my suggestions and doesn't compensate me for it then it reveals their total lack of gratitude and appreciation. It also reveals what kind of people are manufacturing & selling this product. ... show more

    • Disaster Relief if you have serious Electrical Problems
If it wasn't for Priority Start Pro my low mileage 2003 Ford Windstar would have been nothing but junk that is unless I was willing to open the hood and disconnect the battery every time I drove the car and turned off the key. I did everything that I possibly could to find the parasitic drain on the battery by following the wiring diagram in the Repair Manual, and made no headway. After weeks of endless exasperation I felt that there was no end in sight to the electrical problems, which prompt me to to consider giving the car away, or selling the car to the a junk yard. I researched the problem on Internet and discovered the Priority Start, ordered it and installed it the minute it arrived. At first I was disappointed, because after only two starts the Anti-Theft System shut the entire electrical system down that added another level of difficulty that caught me by surprise. I was about to send to send it back for a refund and get rid of the car anyway that I could, so I decided to call the people at Priority Start for the fourth or fifth time looking for answers. It was at that time that I was told about the Momentary contact button that I could install inside the vehicle that would reconnect the ground, simply by pushing the red button that I installed on the headlight switch panel. With that I could unlock the drivers door with a key and push the button before getting into the car, then hit the remote key to unlock all of the other doors, get in and start the car This could all be done without having to turn on the lights or stepping on the brakes to reconnect the battery. I was also advised to replace a one year old battery with a new one that was still under warranty, but could not get a replacement under warranty because it tested out to be in good condition. Since I had decided to buy a new battery I purchased a deep-cycle as the last draw because I had all of the misery with this Ford that I could stand. After I installed the Momentary Connect Switch I figured that it would ether work or it was going straight to the junk yard, I was done trying. To my surprise it works like a champ, no more deed batteries, and it keeps on working, even though the short is still there, it never lets me down, or shuts down the entire electrical system, with a signal that it is being stolen. In this case the Priority Start solved the problem. I highly recommend this application to anyone that needs a viable answer to this sort of problem. Richard Wright ... show more
