Good Plug
Purchased this from Amazon for convenience and it arrived quickly so I was satisfied. If I order the oil and filter for mower at the same time it saves me time and I have them delivered to my door for the mower tune up.

TireJECT cannot work miracles
Size: Compact Car, Mid-size Sedan, Size: Compact Car, Mid-size Sedan
TireJECT is a surprisingly thin fluid that supposedly contains fibers that must help stop up holes. Frankly I'm still confused as to how this stuff can plug a leak, but apparently it does. Tons of reviews say so.
I say apparently because the product did not completely stop a slow leak in my tire, but that's OK. I knew it likely wouldn't. I'll have to replace the tire unfortunately.
I had a garage install four nearly-new tires on my car. After installing, a heavy leak was discovered in one of them. They took the tire off again and found a small tear near the rim/bead of the sidewall. Since the tear would be flat against the rim, they suggested to let them try and repair it with tire patch adhesive and lots of bead sealer. They were confident, so I went for it. It seemed to work, but it went flat a few days later.
TireJECT seemed like the perfect solution to the slow leak since I wouldn't have to disturb the repair. I bought the kind without the syringe and regretted it immediately upon trying to use it. First, the valve stem removal tool broke as it loosened it. I had to buy a new tool down the road. When I went to inject, I squeezed as hard as I could but it just wouldn't flow past the TPM. It also kept leaking out of the flex joint of the nozzle. I had a huge syringe on hand, so I sucked up the rest from the bag, ziptied the hose on both ends and got the rest of the product into the tire. HURRAY!
The tire pressure had fallen considerably by the next morning. BOOOoo. I contacted TireJECT, and after several emails (and long waits in between). They determined their product was not suitable for my use case. They refunded what I paid without me even asking. I really appreciated that.
That said, before injecting, the tire would go flat overnight. So, TireJECT does work to a good degree. I'm half tempted to overdose the tire with another package.
Give TireJECT a try! Though, be sure your situation matches their criteria. If you have a TPM, opt for the package that comes with a syringe. You will need it. Also, throw the cast pot metal, tire stem tool out and get a decent machined one before you do the repair. Thank me later.

Works once again!
Size: Compact Car, Mid-size Sedan
Third time using TireJect on a vehicle, and it's worked perfectly each time. First was the off-road formula for leaking motorcycle tire beads.... then this formula my light SUV with a slow leak until I could get the tire replaced. This was for a stubborn tire that had a leak SOMEWHERE, and usually would lose 10-15 psi overnight after a fill-up. Two days later, still fully inflated and no signs of trouble. This is great because this formulation is also okay for tire pressure sensors. Will continue to purchase this product for similar issues going forward. High quality, durability, and easy to use.
