These are not liquid filled gauges, as claimed. They have a lens plug but come with no oil. They read vacuum, but do not read proper operating pressure. Can't get them past 60psi with the car running and the ac pumping cold air. They both show static pressure, but you can transfer refrigerant. Not sure why. Gauge quality is very poor at this point. Hoses are not very long. Maybe 3' if that. Comes with several adapters, and the port connectors. Port connectors are very soft metal and machining is poor quality. They to not attach smoothly, and can fight you. Vac pump pulls down a solid vacuum and holds. Very quiet too. This setup is fine for the most part, but I wish the gauges worked better. You get what you pay for. Not for use by a pro. Quality is too low.

The vacuum pump works good and the gauges are working ok. The gauge manifold could use better level indicator. I put the pump through vacuum and I later learned that one of my A/C lines has a hole in it. The gauge was reading that it was holding vacuum so I cannot say that it is a good product since it was not reading correctly. I have to check it again when I get and install the replacement a/c line to know if it really works.

Nice quality and it worked great setting up my new mini-splits. However, the listing was somewhat misleading. My system has R410a refrigerant. Although the ad says it works with R134a and R410a as well as others, the kit does NOT contain the adapters needed to service those systems. The ad does not specifically state that adapters are included, but it doesn’t mention that additional parts are required either. This should be noted in the ad so that the appropriate adapters can be ordered at the same time. Just an unfortunate inconvenience that added a week to the job.

I have not had it long enough yet to give it a proper review but I'll share my opinion so far. Seems to be good quality and a very affordable price. All the components operate smooth and well and all finishes are good. I like the case the gauge set came in as it's handy to store and carry the tools.

product looks good ordered can tap for 134a will not work with gauge set I have bought three can tap from three different places none will work with gauge set have not tried the pump yet should have bought american made
