Works great
Works like it should. It truly is a master set and offers more options if needed.

Superb quality.
Awesome build quality. Using a 60 gallon compressor at 90 psi vacuumed cooling system in under 15 seconds. Took less than 1 minute to completely fill cooling system. Superb investment.

Solid Master Set
Really solid master set. I used this to change the coolant in my CRV and GMC Sierra 1500 [had to buy a separate adaptor for the Sierra] and it worked great. I have a small Milwaukee battery powered compressor and it worked great with that set up. The seal was good and the refilling worked great - just need to keep an eye on the new fluid level to ensure the hose remains fully submerged (the hose had a hard bend from being looped during shipping). No frills, just works.

Vacuum device is great. Pressure tester leaks. GM adapter missing.
The vacuum/refill device works great! After using this I will never go back to the old burping/reving/hose squeezing bleeding method. The vacuum method is so much easier and I’ve never had any problems with air left in the system. One tip… when drawing a vacuum, slowly crack the supply valve to prefill the supply line with fresh coolant… this prevents adding a tube full of air back to the system. The internal check valve leaks on the pressure tester. With nothing connected it would loose roughly 1psi per minute. I was able to find a different o-ring in my stash and now it holds pressure much better… it now only looses less than 1 psi per hour… not ideal but much better. This would easily be a 5 star rating if the common GM adapter was included, and if the pressure tester didn’t leak and require a user fix to make it perform acceptably.

Huge kit
This kit covers quite a bit and I ordered the late model Chevy and Ford adapter it didn't come with the overall size of the kit is pretty big

Look closely at the display pictures
This so called "Complete" set doesn't ship with all pieces. 3 pieces were intentionally left out so you would buy them separately to fill the gaps. Parts: 41, 42 & 23 Which totals an extra $60. They are indeed less common than the others. Probly never will need them but still...

The best coolant filling system.
This is a very good vacuum fill and pressure tester for automotive cooling systems. Since many charge-air and electric cooling systems are nearly impossible to fill and get the air out of the coolant, this is a necessary tool.

Good quality
Super good quality for sure, not cheaply made, it’s a bit expensive, but you got what you pay for. I haven’t got chance to use it yet, will update how it goes.
