Review on Dynamic 6 201 Valve Acura Honda by Ronald Cambridge

I was expecting a 4 stem set with the words "4 pack" in the description. The label on the package I received also said "4 pcs". There was only one stem in the kit. Because in the kit (and in the product photo) there are 6 or more parts (step, cap, screw, nut with gasket, gasket and metal washer installed) I don't think that counting 4 is for the number of parts in the bag Description "Long valve" does not mean this stem is longer than say "Anxingo TPMS tire pressure sensor metal valve stem repair kit replacement for 2 3 5 6 MX -5 CX-7 CX- 9 RX-8 Mitsubishi Lancer Outlander VS-MA02"; anyway it's a bit shorter. I have 2017 "Lors Auto Parts LAP100 - TPMS Valve Stem Kit for Siemens Type Sensors ( Ordered Pack of 1)" and this part works (holds air in tires, connects to factory TPMS module; same length as Anxingo part), but inflator stations often can't push far enough to seal tires properly , making it difficult to inflate the tires.(My 12 volt infla (tor (slow) and my air compressor (at home) work fine with the shorter stems.) The car is a '09 Mazda 5 with stock wheels. There are no problems with factory barrels.
