Works great, tighten it together good before using.
Very easy to use. Some reviews said it leaked.things I learned. Tighten the pieces together with pliers or channelocks, if you tighted it together by hand the 2 pieces will leak. Only hand tighten the entire assembly to the valve stem. Do not try to bleed air out of the tire while filling it. shut your pump off, then bleed the air from tire, when the air is bled, restart fluid pump. 1st tire was learning curve, I lost about 3 oz of fluid 2nd tire, I lost no fluid at all Entire process for 2 tires was about 30 minutes. It is well made, sturdy and it works great if you just think ahead.

Works as expected
Used this to fill about 180 gallons of RV coolant into my tractor tires. I used a drill operated transfer pump and it worked really well. No complaints.

Easy to use
Perfect for filling your tractor tires with water. Screws right onto valve stem and the water hose and fill and just release pressure every so often . Great product

Great item
I put 9 gallons of beet juice in my tractor tire that had a failed valve stem. It took a while but got the job done to add ballast to my tire. I used beet juice because it is heavier than water and is not corrosive.

Works but leaks
Got the job done but made a real mess since the pressure release mechanism leaked antifreeze all over the floor.
