    5.0 out of 5 stars Great for Beginners and DIYers, with Some Quirks
    Reviewed in Canada on November 30, 2024
    Verified Purchase
    This set is a solid choice for basic AC maintenance and diagnostics. The gauges feel durable, and the hoses have a good length, making them convenient for reaching tight spots. It’s a versatile kit that works with multiple refrigerants like R134a, R12, and R502, which adds to its usability.

    However, there are some quirks. The instructions could be clearer for first-time users, so expect to watch some videos or do a bit of research if you’re new to AC work. The couplers can be a bit stiff, especially on initial use, but they do create a reliable seal.

    Overall, this kit is well-suited for beginners and occasional DIYers. It’s functional, cost-effective, and a good starting point for tackling AC systems at home. Just be prepared for a slight learning curve if you’re unfamiliar with manifold gauge sets.

    For the price these are great units. I work in HVAC and have yellow jacket manifold for residential AC. This set has the automotive adaptors, a case and everything. Used to replace compressor in my First Escape. Great buy for the money.

    4.0 out of 5 stars Fair, considering the price
    Reviewed in Canada on August 3, 2024
    Verified Purchase
    This product works as advertised (for the short term). I gave it a 4-star rating only because the price is so low.

    That being said, the plastic seals in the hose fittings do not compress and seem to be very low quality. Any tension in the hose, the hose will easily unscrew and your freon will leak out. You have to keep checking the tightness frequently.

    If you look at the male connectors on the manifold, you will see rough machining marks and damage from mishandling. Each time you connect the fittings, the seals get damaged a little more. I reached out to the seller about purchasing replacement seals and they have not responded.

    It's considerably cheaper than a professional set and you have to work with that.

    If you know what you are doing, this product is perfect for R134A. It is cheap and does what you need. I had to repeat the process of discharging, vacuuming, holding vacuum and even recharging few times because there was a leak in my system and it did a perfect job at all times. Helped me a lot during the process.
