Bought twice.
Decent enough as long as you don't over-tighten with them. I bought a second set because a mouth breather I work with broke the tab off one of them. They work good and I have used them for many years before the borrowed one got broke.

They work on my small propane bottles to refill.
Great deal it's that simple. Thank you

Product sheared on a siezed schrader valve on first use
The metal isn't great quality. Broke on first use on seized Schrader, can't entirely blame the product but still is relatively fragile.

Great Tools
Good variety of tools to remove the tamper-resistant caps on shraeder valves on condensers. Different sizes, one is bound to fit. Reasonable price for a necessary tool.

The Blue Tool Was What I Needed
No need to take pictures but if you need schrader valve tools, this kit has them all. My 2002 Ford Ranger low side has the biggest schrader valve there is out of all those sizes and just what I lacked. It was also tighter than heck and I had to put pliers on it to get it to turn and it held up fine. No complaints. Five Stars

Schrader core tool set
$40 on the tool truck, $7 on Amazon and people try to say I should be loyal to the tool trucks. If I could tell a difference or if the price difference was at least closer, maybe. But these work and I could by 6 sets, but doesn't look like I'd need to since they have been working great. Jimmy, Making it work

A/c valve stem removal tools found here at an excellent price than most suppliers. I use them often and havenโt had any issues with them.

We are using it daily at the County Public Works shop where we have over 50 vehicles with air conditioning and we've had a record heat wave

Could not stamp up to the force needed to properly tighten the a/c valve.
