        Easy install. Does what it is supposed to do.

        The product installed in less than 10 minutes and worked flawlessly. The provided instructions from the vendors website was not organized well, but had all the essential information. A couple of good YouTube videos are available to help substantially. I reset the tire size and leveraged the ability to turn off the auto-start feature.

        100 percent worth it

        First we had to return the Tazer Lite, for the Tazer Mini. Extreme Terrain setup the return and got our new unit out to us swiftly. We received the mini and configured our target settings and everything works beautifully. Our primary reason to purchase the unit was to solve hyper flashing with our sequential led turn signals. I am happy to report it works like a champ.

        Works perfectly

        All the programmers are overpriced in my opinion but it did its job and came with some bonus features

        2 2018 Wrangler - Hotfoot2 Installation Time: Less than 1 Hour

        Would REALLY like to get the whole system

        Ordered. Received without the adapter to plug into the diagnostic port. Called them,They told me to send it back as a return. I did so. Received a replacement that was identical to the last order -- missing the adapter to the diagnostic port. Told me to return it, and hope that the right thing would happen, OR I could buy it again and perhaps this time it would be right, after which I could return the wrong stuff. Reluctant to order for my new 2019 Rubicon.

        5 2018 Rubicon - RobertD Installation Time: Less than 1 Hour

        Worked for me.

        Tried to reboot my jeep by disconnecting the batteries and got a check engine light instead. Tazer fixed that and reboot feature is nice. Works on the stupid auto start thing to. One of these days I will be getting bigger tires. Went to their site and got the firmware updater program and updated it before I used it, was simple. Seems like a lot of money for some electronics but what else is new. Didn't want to take it to the dealer for my first oil change with the check engine light on. Who knows what they would want for that.

        5 2018 Wrangler - tk2fast Installation Time: Less than 1 Hour


        First had a slight problem with the serial number showing up. Turned out to be a bug in the new firmware update. Tazer took care of it immediately and were very kind and apologetic. There are reviews knocking this some but I really don't understand, saying it's hard to install. Really, it took me a whole 10 minutes with the most being spent on removing the two electrical plugs from the SGW as they were tight on my JLU. Then it was on to the programming. Took a few tries to get the hang of it but then was able to kill start/stop -- kill seat belt ding -- set my front turn signals as DRL's -- change tire size for correct spedo readings -- and change bulb types from halogen to LED. This thing is awesome. Period. Just need to spend a little time to understand but there are some not willing to do that so it's their loss, but then they crab that it's a problem with the device. Some little things are likely to crop up with any re-programming but Tazer will take care of it. I'm a believer as they solved my problem in less than an hour.

        5 2018 Rubicon - Damien Installation Time: Less than 1 Hour

        It Works

        As the title says the Tazer JL Lite works as advertised. I don’t need all of the functions. First off I like my start/stop. It saves me tons of gas in DC metro stop and go traffic. I have the turbo 4 which I have heard is way smoother than the v6 version. The light show is a fun gimmick. The winch mode is useful. The TPMS self adjusting is nice to have. And the main reason I got the Tazer adjust the speedo b/c I upgraded to 35s. Adjusting speedo is a process of finding the right size in the menu then driving it a few times with a self speed rating gps unless you have access to a real radar. Basically I would recommend this product to my best of friends.

        Tazer JL Lite

        easy install, just follow the online instuctions and you can reset speedometer to match your aftermarket tire size and if you have a manual transmission like me, turn off the engine on/off function when you come to a stop
