Very good quality

Just what I expected

Work great, big time saver

Works for me!!!

Seem to be good quality fit nice no complaints.

Junk product & poor quality control, but delivery was quite quick! I ordered two sets of these "HVAC" copper fittings. Both were delivered quickly the next day. They get 1 star for quick delivery. The fittings were very thin gauge material and bent/misshaped easily while brazing in place. That in and of itself was disappointing, but I was in a pinch and couldn't purchase them locally since all the HVAC supply houses locally were shut down for the weekend. I reluctantly pressed on and used the elbows and couplings from the first box without further issue. Upon opening the second box and after using one of those elbows, I found that the two Straight pipe coupler fittings they included were not the correct size. This box had mostly all HVAC fittings (HVAC uses outer diameter sizes) except the for the two straight couplings. This box incorrectly included 3/4 inch inner diameter fittings. For those of you unfamiliar with the difference, 3/4 Inner diameter and 3/4 outer diameter are significantly different in size. In a nutshell, my HVAC repairs came to a screeching halt and I had to wait for the local supply houses to open up on Monday to get what I needed. That is, to get what I had already grossly overpaid for and should have received in this item/box but did not. I suggest you buy elsewhere for better quality, better price, and better odds of getting what you need the first time. Conversly, if you dont mind junk as long as you get it fast, then this is a purchase meant just you. Unfortunately, because I used some the items from both boxes, I doubt the seller will do anything to make amends. I will be contacting them directly on 5-23-2025 and will update this review after that, if they make any attempt of good faith at all... If you see no update here, then they have still taken no action to show concern for their failure.
