Read the directions. You need to turn the valve fully counter clockwise
to retract the piercing pin away from the can. Then you screw the valve
tap onto the can. Turning the valve clockwise will lower the pin into
the can piercing it effortlessly. Screw all the way down and ten open to
dispense into system. When empty, close the valve, disconnect the hose
form the suction port and then repeat above for the next can.

Take those three empty cans and that Chinese can tapper back to Wal
Mart.
They'll give your money back.
I returned a pair of jeans after six months when the zipper just let go
along one side.
I often wear suspenders and the clasps never last, after about a month
they just give up.
I don't give up I go and get my money back.
The only way you're going to get better quality is to cost them money.
The coolest thing about Wal Mart is that you can get a refund faster
than
standing in line to buy something.
