Great and easy to use in my opinion ! I had to file bevel flat after using drill bit otherwise rubber washer didn't sit well, and air was leaking. Got the job done, saved money, and hoping for the fix to last a long time!

I had the classic broken TPMS valve stem failure this product is designed to fix. Recommend you watch the You Tube videos and decide if you have the necessary skills and tools to do the job successfully. I have a high speed drill and access to compressed air. All the other needed tools are in the package. The tricky part is tapping the remainder of the broken stem. It took me a long time to fully tap the stem properly and not break the tap or destroy the remaining part of the stem. If you have experience tapping metal, you will understand that part of this job. It may be more difficult if this is the first time for you! You can't use any lubricant during the tapping process so you must take your time and run the tap in very slowly only cutting a quarter to a half turn at a time and removing the tap to clear the cutting chips. You will need compressed air as blowing from your mouth will not do the job. It was helpful to remove the Schrader valve from the repair part and I test fit the piece several times so I knew that I had tapped the stem deep enough to make sure the o ring touches the stem to seal. Finally, I allowed the included thread lock to dry for an hour before refilling the tire with air. No leaks and a perfect repair. I understand that you may be able to have the valve stem replaced, however that requires the bead to be popped off the rim which requires more tools and effort than I was willing to chase. This repair is most likely cheaper than a service charge at a tire shop. I hope this repair will last until I need to replace the tire and I will have the TPMS replaced at that time. Good luck!

Bottom line if your cheap like me try this. But before you do verify it's your valve stem that is leaking and not leaking out at the same spot you put air in. That could be dirt or a loose valve stem. So a little dish soap in some water and dump it on and look for bubbles. It's easy to use if you know how to use a drill. Follow instructions, they work. And just an FYI. Most cars have a TPMS rest button if the error won't clear after inflating all tires and don't forget the spare !!! Goggle your make model and year to learn how to reset.

I used on a tire when I suspected my tire had a valve leak, turned out that it had a leak around an old plug. Before replacing the tire I had to repeatedly inflate the tire, this put stress on the replacement stem, which finally just broke off and tire going flat. thankfully this happened at home and not at the air station at some gas station since my vehicle hasn't a spare. To fix I replaced the replacement, thank goodness the kit comes with 2 valves. Hence forth, if the new tire should need air I will only use a screw on type pump which is gentler than other types.

Received the item ahead of schedule, I took my time doing the repair, the little rubber washer I think was old or too week, it malformed even before reaching the required torque. I let it set for 30min. Inflated the tire to 35psi checked for leaks with soapy water, all good. Put the tire aside for 90min rechecked the air pressure which was unchanged , then reinstalled the wheel. All good. I don't see how anyone could have any problem with this if they take there time, follow the directions. All good.
