compressor was not working probably although i have added a recommended oil before usage... Manifold Gauge Set ( ok(

This is a quality kit, with a couple of exceptions. Firstly, the instructions aren't super clear. You can remedy this by finding Sam A.'s review on this product page - he's done an excellent job clarifying the necessary steps. It's not rocket science, and it will all make intuitive sense in the end, but until you've actually done it, you'll probably be a bit in the dark about what all of the different gauges and hoses do. Also watch the video "How to Properly Recharge Your AC System" by ChrisFix on YouTube for a general overview of how this all works. Note that he's using a different manifold which works a bit differently - mainly that the yellow line is used for both drawing a vacuum and adding coolant. In this product, you also have a black line that's dedicated to connecting to the vacuum pump (using an included adapter - the end fitting won't connect directly). Secondly, as Sam A. mentioned, the included can tap is basically worthless. You'll need to buy one for "self-sealing" R134a refrigerant cans that are now ubiquitous, at least in modern vehicles. You can get that at Harbor Freight, any automotive parts store, or here on Amazon. Just search for something like "self-sealing R134a can tap." That will probably have a different thread fitting, but this kit also includes an adapter that connects the tap to the yellow line. It basically comes with everything you need except for refrigerant cans and the correct can tap. That said, the build quality of the pump is decent, the manifold is excellent, and the lines are all sturdy and seem built-to-last. Mine gave me no problems at all as I fumbled through the full repair process over a few weekends. While your A/C system is open/depressurized, it's probably a good idea to replace the Schrader valves on your high- and low-side service ports, at least if your vehicles is older than maybe 5-ish years. These are common leak sources. Also make sure they're still capped. Mine weren't, probably thanks to a scatterbrained mechanic somewhere along the way. You can also find replacement cap kits (often also with common Schrader valves) here on Amazon. Servicing your own A/C is not a particularly simple task to learn by yourself, but once you've done it, it should be pretty simple going forward. It took me a lot of YouTube videos, instructions, trips to the auto parts store, etc. until I had all the right tools and materials to get it done. But now that I've done it and see what's involved, I could probably do it in the future in at most an hour of hands-on time.

The extra item you'll need is the "Yinleader 500w Voltage Transformer" at £42 to provide 110v for the vac pump which has the amps/watts headroom to power the vac pump. My 31yo truck vac'd down nicely with the pump, after replacing a worn through high pressure ally pipe, a new condenser & drier. Having the black AND yellow pipes means that the pump has it's own vac pipe, and using the vac'd system, you can add oil to it on the yellow vac'd line, drawing in the oil under vac, without pulling in air. In all a great piece of kit.

I've only used this kit twice and it works great. Can't say how durable it is but for the amount I use it should last.

Comparing all the options online, this set by far has been the maximum bang for buck ratio. Take away all the pros and cons, and you are still in the green with this one. Not overly priced, includes all the necesary adapters and hoses, and provides vacuum with a 4th hose being black for suction. I was able to fully restore lost freon after a AC compressor replacement for an 7 year old truck. Not that old but the bearing inside the compressor pulley was showing early signs of failure with bearing noises/clicks. Regardless, one job alone was given an estimate of $250. This kit saved me $100 and now I can do more tune ups for family/friends. Only thing I found annoying about the hose connections was how flimsy and loose they can get even hand tigthening as much as possible. Wont leak but a few jiggles and tosses and it will twist open on its own so guess that is part of the price tag.

The compressor is 110v and us plug. So it’s unusable for uk at 220v. In the pictures of the product is blurred so you don’t clearly see. Waste of time and money as I can’t use it
