Customers are dissatisfied with the leakage of the electromechanical gauge. They mention that the low side worked, but it leaked badly. The high side quick connect leaked while stuck in place, and moisture causes an AC system to leak. The threads leak, and the set is useless for doing a complete diagnostic on an A/C. The fittings would not seal, and there are 2 pieces of the seal.
"Moisture causes an AC system to leak. You pull a vacuum on the system to remove any moisture possibly in the unit...." Read more
"...All three hoses tested okay, a small leak, it took several minutes to notice drop in pressure gauges, three quantity pressure gauges were on the “..." Read more
"Fittings have to be tightened with plyers or they constantly spin off. I think it's cause of the nylon fitting seals are new and spin easy...." Read more
"...Seals were all good and I was able to successfully vacuum test my work for 12 hours without any leakage in the system or the gauges/hoses...." Read more
Customers are dissatisfied with the fit of the product. They mention that the fittings sent with the kit don't work, the guards didn't fit either of them, and the fitting can be hard to put on without releasing R134a into the atmosphere.

"...the pump and 134a adapter had the same threads, but the guards didn't fit either of them...." Read more
"...And the adapter that comes with the kit doesn't fit the can tap, so I bought this one that fits well (less than $6):..." Read more
"...The fitting can be hard to put on without releasing r134a into the atmosphere which is bad...." Read more

There was a problem filtering reviews right now. Please try again later.
I had no trouble putting it together or hooking it up, the high side slid right on without any struggle. Seals were all good and I was able to successfully vacuum test my work for 12 hours without any leakage in the system or the gauges/hoses. Recharging the system was a breeze with the can tap adapter (not included!) and I felt much better doing the recharge with the gauges versus the prior work I've done with a single low side can tap and gauge.
The high side connector did indeed stick after running the system for 30 minutes while I recharged the system and the root cause is very clearly thermal expansion. If I hook up the system when the system and car are cool, it pops right off without issue. Once the car and the system heat up, the connector and hoses heat up and then it becomes more difficult. In my case, I waited 5 minutes and the quick connect released without much fuss. I'm sure there is an engineering solution to this problem, but for the price I'm ok with waiting a few minutes. It gave me an excuse to have a beer and celebrate a successful AC repair!
Little caveats: 1. the fittings on the back of the manifold that are supposed to be for storage of the lines are not practical, because they are threaded fittings, not 134a ports. So you'd lose the actual end pieces because you would have to unscrew them in order to use the "storage ports." No big deal, I just don't use them, I wrap it all up and stick it in a cabinet anyway. 2. I did find the high side port to be a little finicky, nowhere near the disaster that other reviews describe, but I did have a little bit of trouble with it. I wear gloves when working with refrigerant, because common sense, but did experience the effect of the high side pressure venting out of the manifold and hose after some considerable effort to disconnect it from the car. I will monitor this and update the review as appropriate. At this point, I would recommend these for a DIYer or light user, with the low price in consideration.
Mfg contacted me regarding my two complaints: I needed the Celsius version was my fault as it is stated in the product description- just be sure you see it. As for the adapter to fit a T-fitting on gas can, it does not come with the product rather the product is configured as std 134a threading. T-fittings for those 12 ounce gas cans commonly sold in automotive stores are different For this inconvenience, the mfg gave me a partial refund without asking for it. This company stands behind their product and customer.
Additionally, I've been using the gauges for several days now under constant pressure and very happy with the product. Unlike other gauges I purchased in the past from HarborFreight (junk that leaked), these are performing perfecting.
Changing my rating from 3 to 5
1. Connecting both the high and low ports with the engine off resulted in the two gauges reading significantly different pressures (~25 psi delta on a ~70 psi reading). The static pressure in the system should be the same on both the high and the low side so one of the two pressure gauges is inaccurate and I have no way of knowing which one.
2. Like some other reviewers, the high side quick disconnect fitting got stuck on and the ensuing 5 minute struggle to disconnect it drained a significant amount of refrigerant out of the system. After the first incident I did not use the high side connection again. The low side disconnect worked flawlessly all three times I used it.
great

In other words, the fittings seal properly finger tight and there is no leaks until you start moving the hoses around. Next time I use it I'll have to find a way to prevent the threaded fittings to loosen up.
