Works better than expected for a low priced product.
It has worked flawlessly for my 2018 MKC (315mhz), 2015 F-150 (315mhz) & my 2024 F-350 (433mhz). It triggers the sensor and I have to wait for it to stop flashing, then move to the next tire and push the button again for each tire. This worked for all the above vehicles. From another Amazon Review for the Schrader TPMS Sensor which is extremely helpful if changing a sensor: The usual TPMS relearn procedure (Put vehicle into accessory power mode, press hazard light button 3x) would not allow my truck to learn the new sensor ID. As it turns out, there is a different TPMS relearn procedure that is require when replacing a sensor (and, consequently, changing the ID of the sensor within the vehicle computer). You need to do the following: 1. Place your vehicle into accessory power mode by either turning the key on without starting the vehicle, or (for push button start vehicles) pressing the start button without engaging the brake pedal. 2. After placing the vehicle in accessory power mode, press and release the brake pedal 3. Cycle the accessory power off > on 3 more times 4. With the accessory power on again, press and release the brake pedal one more time 5. Cycle the accessory power off > on 3 more times. After the final "on" cycle, you should hear your vehicle's horn honk, indicating that you've entered TPMS learn mode.

Would buy again
Pros: - quick connection to sensor and car - easy to use - instructions provided - no issues with battery life - product feels durable if dropped but I did not test it - tire pressure was immediately displaying on car’s screen Cons: - instructions were slightly off for Ford’s and the instructions were not proof read Overall: I would for sure buy this again if I needed another one. The instructions weren’t perfect but they were good enough to get the job done. For my car in particular, I had to put the sensor against the rim behind where the valve stem is instead of the tire wall like the instructions show. See my photo of placement location.

Works on some not aftermarket
It works on my F250 and Explorer. It will not work on the aftermarket sensors that I have.

Fast Easy Tool, Read my Review for Chevy Colorado Usage
This tool works and it is easy to use. Below I outline the steps for a 2016 Colorado. See pics after reading steps. I was able to reset my sensors in under a minute. First step is to press white button on device and make sure light is lit for “G” for GM. If “F” for Ford lights up hold white button again for over 2 seconds until “G” lights up. Step 1 Ignition on with motor off. Step 2 Navigate to tire pressure menu. Step 3 Hold Check mark until horn beeps. Step 4 Place tip of tool on front driverside tire touching the tire and 1 inch to the left of stem. Press white button once, your cars horn will sound. Wait until the light turns off before next step. Step 5 Repeat in this order. After Front Driver, Front Passenger, Rear Passenger lastly Rear Driver waiting each time for your cars horn to honk and LED on tool to turn off. Step 6 When you are done with the Rear Driver side tire horn will honk several times, you are done. If this fails your tire may be to low and you should have the recommended tire pressure or more before you begin. The tool does not come with a 9v battery. Plan on having one available before you may use it.

Ford Owner-This one didn’t work. I returned it and bought a different one that worked immediately
Save yourself some grief. I have a 2008 Ford Explorer, so an older car, and just got a tire sensor fault error on the dash display. It turns out my suv has the band sensors. I tried scanning my tires over 2 days with this tool, and it only found one sensor twice. I tried it on the F setting, on the G setting, pointing the antenna at the tire by the valve stem, pressing the tool sideways on the tire by the valve stem, then repeating the same process on the opposite side of the tire 180 degrees from the valve stem, on each setting, in each position. I tried this on each tire, and…nothing. I wasn’t sure if it was the tool, all of the sensors, or my inexperience, but I decided to order a different looking tool, because I mainly see 2 styles of these relearning tool in the inexpensive variety. I ordered a different bright green tool because I figured it would be easy to find when I misplace it a half dozen times when I’m getting frustrated. I ordered this one: JDIAG TPMS Sensor Tool, TPMS Relearn Tool for F150 Auto TPMS Reset Sensor Programming Training Tools Tire Pressure Monitoring System (TPMS-19 / 8C2Z-1A203-A) I put the car in Train mode, put this sensor next to the valve stem on the left front tire, and…nothing. Then I placed it on the opposite side of the wheel, 180 degrees around, and…Bingo! I can’t believe I wasted 2 days trying to get a weak JDIAG 2IN1 TPMS Relearn Tool to work! I went to the next wheel, and couldn’t get anything to scan, so I went to the 3rd wheel. Bingo! Next, the 4th wheel. Bingo! I concluded that my wheel #2, Right Front, is the faulty sensor. The 8C2Z-1A203-A tool made it super easy. So, if you are reading this review, don’t buy the tool which this review is written under. Search Amazon for the following tool and buy it if you have a Ford! Again, “ JDIAG TPMS Sensor Tool, TPMS Relearn Tool for F150 Auto TPMS Reset Sensor Programming Training Tools Tire Pressure Monitoring System (TPMS-19 / 8C2Z-1A203-A)”

It's a great gadget. Note: IF you have a Ford F150, try the GM setting if the Ford one doesn't work.
[March 2025 - My review of "JDIAG 2IN1 TPMS Relearn Tool Super EL50448 for GM and for Ford Tire Pressure Monitor Sensor TPMS Reset Tool 2025 Edition"] We have a 2011 Ford F150 Platinum, and for several months the TPMS error message had been on the dashboard display every time we started the truck. Our research showed that the message could simply be due to a dead/dying battery (apparently they last roughly five years) I confess - we're cheap. Genuine Ford TPMS units are over $50 each, so I took a chance on much less expensive ones from Amazon: "9L3Z1A189A TPMS Sensors, 315MHZ Pre-Programmed Tire Pressure Sensor for Ford F150 F250 F350 F450 F550 2009-2016 Escape 2009-2019 Fusion 2010-2016 for Lincoln MKX MKC 4pcs" The brand: ISINLASSO... They have various part numbers so be careful which ones you order. They're supposed to be pre-programmed, and a set of four is only $24.59 at the moment (March 28, 2025) which seems about average for non-OEM units. When we had new tires fitted a few weeks ago we got the fitter to replace the TPMS units as well. Initially, I bought a small gray rectangular TPMS relearn/trainer clicker on Amazon for about $13 because it looked like the ones in 'how to' videos, and it's popular on Amazon with good ratings. Unfortunately, that little gray clicker didn't work on our truck's TPMS units, and I was worried in case the error message wasn't being caused by a faulty sensor in the first place, or I might be forced to buy a set of Ford OEM sensors and pay to have them installed, which would have been annoying, to say the least. Before doing anything rash & expensive, I ordered this very different gadget because it claims to work with Ford and GM sensors. Note - You'll need to install one of the small rectangular 9V batteries with the two terminals on the top, which is a bit inconvenient unless you're battery hoarders like us. However, once that's done, the instructions explain how to put various vehicles into the required 'Tire Training Mode' before using the gadget. There are several 'how to' videos attached to this product's Amazon page, and various YT videos show you how to do it as well. Hubby was able to do the TPMS retraining in about five minutes. It would have been even faster but he tried it a couple of times using the Ford setting (for obvious reasons!), which didn't do anything. However, the instructions said the GM setting works on some Ford F150s, so he tried the GM setting once and it worked immediately! No more TPMS error message anymore. Yay! The VERY short version: This Ford/GM TPMS training gadget worked for our non-OEM TPMS units on our 2011 Ford F-150 Platinum, using the GM setting, not the Ford one. So, if you're having no luck with the Ford setting, I recommend trying the GM setting before returning the gadget!

I was amazed! Re-program tpms yourself!
This little piece of equipment saved me about $700 by allowing me to re-program my tpms sensors on my 2012 Ford F150. Took less than 5 minutes and worked perfectly! Outstanding job guys!

Excelente
Funciona correctamente, Ford explorer sport 2018, tal cual seguí las instrucciones y a la primera quedaron las 4 llantas programadas... La historia detrás fue que un sensor se descompuso y lo tuve que comprar en Amazon también, tuve que rotar las llantas y ninguno era el correcto en el tablero.. Lo que tuve que buscar el programador correcto, en cuanto llego lo utilice, y en 5 minutos quedó todo listo incluyendo el nuevo sensor..
