Review on XtremepowerUS 4CFM Air Vacuum Pump HVAC A/C Refrigeration Kit AC Manifold Gauge Case Set R134a Tap with Leak Detector + Carrying Tote Bag - Premium Quality by Kevin Johnson

Because the seller requested a 5 star rating before I had a chance to use this product they are losing a star on the top right. I hate it when a seller asks for a 5 star rating without giving the buyer time to use the item. Glad I haven't left a review yet. After unpacking and trying to connect everything, which I discovered very quickly, I can't use the sensors to actually add refrigerant to my truck. The connection on the yellow hose does not allow adapters. Both adapters and the valve that leads to the refrigerant are NOT screwed on. In other words, I need to add refrigerant using a different set of gauges. Waste of money for anything other than vacuuming the AC system UPDATE: After vacuuming my AC system on my truck and charging the system, I found that the high pressure gauge wasn't even working. send the whole system back
