Gets the job done.
The product is economically priced and sealed just fine, I used them used on a LG 134a refrigerator. Caps were built well and I had no problems with the included schrader valve cores. The only thing wrong with this product is how thin the tubing wall is. It can handle 134a pressures but it does not bend at all, it will kink no matter how you try to bend it. I would give this product a 4.5/5 but I am rounding up to a 5.

Working great
Copper a little thin

Nice to have on hand for projects.
Just as described, however why I gave only 4 stars was of the materials used. The copper tubing was in my opinion very thin-walled and as I was trying to silver solder the connection the fitting would become soft and plastic-like at just about the same time the silver solder paste would start to melt. However, the workmanship product was good and maybe someone more skilled at soldering could get better results.

great product
yes the copper is thin, but you don't heat up on the stem of this anyways, I used MAPP gas on it and worked great

Good quality for the price. Fast shipping
Good quality for the price. Not as thick of copper tubing as more expensive ones but work just fine.

Wall Thickness was lacking
Needed some valve stems for testing, so ordered these in a pinch. As others have stated wall thickness is very thin, so for service use I'm sure it's fine but for testing where higher pressures are required it was lacking. Had to sheathe the stem in a 5/16" diameter outer tube to get the stem to make pressure.
