Rated 5.0 out of 5.0 by Stan standard copper fitting
With proper prep, these fittings will work with any copper pipe. I have used this brand on several houses that I have owned over the last 25 years without any issues, works even with 70+ year old copper plumbing. You need to sand and flux all connections before soldering. Leaking connections is a sign of incomplete/improper prep or soldering.

Rated 5.0 out of 5.0 by FixItAll I don't understand the negative reviews
I have been using copper tubing and fittings for years and I see NOTHING wrong with these. These are the same fittings that Nibco has made for decades. No, they do not fit perfectly on any unprepared pipe...fittings rarely do. Pipes DO slightly deform from the pipe cutter and they require cleaning/sanding to insure a proper joint, EVEN if the fittings seem to fit perfectly without preparation. It is not just the cost of the copper itself that has led to the decline of its use for residential plumbing but it is MORE difficult to install, especially if done correctly.

I now see why it's called a "Sweat Elbow". You break a sweat trying to get these fittings to work. These things are impossible to put on. I had to subtract 1/16" from each pipe length in order to get them to come out to the right measurement. Not to mention the sanding and reaming I had to go through to get these fittings to 'fit'. The only reason I got these 90's was because it was cheaper to get them in a pack of 10.
