    Works exactly as advertised; well worth the $90 to not press that stupid button every time.

    Start/stop eliminator

    Posted by Scott Hendrix on Apr 6th 2021

    Priced a little high, but not enough to make me hesitant on purchasing. Was exactly what I've been looking for. I like still having the option of using the feature, though I don't foresee there being a situation where I will. I'm looking forward to other products from 4d tech that work on my 2021 f150.

    5 Star Service!!

    Posted by Sterling on Apr 6th 2021

    I ordered my start/stop eliminator for my 21 F-150 and they shipped it next day. I get a lot of packages, so I track everything, and I noticed the following week, my package had arrived at their local distribution center, but still hadn't left! Again, for an entire week! I reached out to 4D and they apologized and informed me they'd stay on top of it. And they did. I never had to reach back out. They continued to track it for me and assured me if it doesn't move, they'll send another. Finally, the following week, it moved and they reached out, **again, without me asking** and informed me that it's moving again, and out for delivery. I installed it immediately and it works as advertised. Used their video link/instructions to install. Super easy.

    Thanks so much to 4D for going above and beyond! I've dealt with a lot of companies whom wouldn't even look again, or reach back out so fast. You're Customer Service is 2nd to None and I will be recommending you to everyone I know!
