Easy to Use
Easy to use, cheap, and gives me peace of mind

Excellent tool
I am truly impressed with this tool, first of all, it’s very inexpensive and pays for itself after one use. You just opened the back install at 9 V battery and put the car in learning mode. And then you have to go to each tire impress a button and it will reset the tire. The reason why I know it works. Is that one tired kept giving me problems and wouldn’t reset, so I replaced that sensor, and then scan it with tool and it set it. So obviously it was a bad sensor. And the tool works just fine. Great investment and worth the price.

Being able to use it.
It was to hard to reset the sensors on the tires.

Don’t but this product
It doesn’t work tried a few times and I even took it to a tire shop so they can see if they can get it to work. And NO it didn’t work for them either. So don’t waste your money on this product. 😡

Didnt work for me but not sure the tool is the problem
Got this TPMS relearn tool for my Silverado 1500 because I thought it would save me a trip to the dealership. The tool itself seems fine and the instructions are straightforward. The sensors aren’t registering for some reason but I honestly can’t tell if that’s a problem with the tool, the sensors themselves, or something else in the system. The compatibility claims for 2006-2026 GM vehicles sounds good, but I can’t tell you for sure if it works or not. It might work great for some people and not at all for others depending on their specific setup. If you do grab one, just know that it might not be a guaranteed fix for every TPMS situation. It’s worth trying if you want to avoid the dealership, but don’t expect it to work magic every time.

Does not work on 2012 Chevy Cruze
I was very disappointed with the FIRSTOOL EL-50448 TPMS Reset Tool. I bought it hoping it would make resetting my tire pressure sensors quick and easy, but it turned out to be frustrating and unreliable.First, the tool is extremely inconsistent. I followed the instructions exactly, put my vehicle into TPMS relearn mode, and tried multiple times on each tire, but the device barely responded. Sometimes the light would turn on but the vehicle wouldn’t recognize the sensor at all. I had to move the tool around the valve stem repeatedly just to try to get any response, which made the process far more difficult than expected. Many users report the tool can be “finicky” about positioning and may require moving it around the valve stem before it triggers the sensor. (BestViewsReviews)Another issue is compatibility. Even though the listing suggests it works with many vehicles, it didn’t work properly with mine, and I later discovered that some versions only support certain model years or systems. Some buyers also reported that the tool failed to train sensors on certain vehicles or didn’t work at all despite following the instructions. (Walmart Business)The build quality also feels cheap. It requires a 9-volt battery that isn’t included, and even with a fresh battery the device still struggled to function reliably. For a tool that’s supposed to save time and avoid a trip to the shop, it ended up wasting more time than it saved.Overall, I wouldn’t recommend the FIRSTOOL EL-50448 TPMS Reset Tool. It’s inconsistent, confusing to use, and not as compatible as advertised. In my case, I ended up going to a tire shop anyway to get the sensors properly reset.

EASY TO USE
I can’t believe how simple it is to use. Just pop in a 9V battery, get your car into learning mode, and then it’s just a matter of going to each tire and pressing a button. It worked perfectly. The fact that I used to pay tire shops to do this exact same thing for years now feels ridiculous. This tool pays for itself after the first use. A must-have for any car owner!

It’s easy to use and saves time.
Does Exactly What It Promises. This TPMS tool is a great time-saver. The instructions are intuitive: get the car into learning mode, then follow the correct sequence for each wheel. The key is placing the tool at a 90-degree angle to the valve stem before pressing the button. The audible horn beep after each wheel provides clear confirmation.This tool has been great.Highly recommend.
