Works great

I use it to check performance of new installation of a/c units in homes. Works great

Great buy!

Great gauge set, already put into work pulling down vacuum and pressure testing with nitrogen, checking temp loss on a reversing valve. The gauge set is an all around great buy

Very easy to set up and use, I recommend also buying a low loss vavle to go with it!

Easily the best deal I’ve seen for a digital set. Works simple and perfect!

Really nice tool, but you'll need R134a hoses for cars

I'm a shadetree mechanic and recently the weather has been unnecessarily hot! OK perhaps it's hot by necessity but it's been hot out! I ordered this manifold set on a lark and I'm pleasantly surprised. Now you will definitely need R134a hoses if you intend on working on US automobiles but from what I've read this gauge can work with more types of refrigerant than I knew possibly existed! In the end I'm happy with my purchase and I do recommend this to someone who is likewise interested in a manifold set.

They work

So far so good hooked up to r-22 found target SH to the T...clamps work wonders...

Would Recommended

This is Good tool HVAC and refrigeration technicians. It has all features in one single unit. Used several times works great. Very accurate The clamps work great. they held up pretty good . no problems.This has exceeded my expectations! This unit was worth every penny. Would recommend to other technicians out there.

Great Digital manifold for the price

Very nice set for the price I would buy another set if something happens to this one

Give it a chance

Unit looks impressive for the price. Husband has yet to use it but seems very pleased.
