Rated 4.0 out of 5.0 by Grrumpa A great safety solution for the DIY'er
A great product with solid credentials to back it up as the safety product for those of us still dealing with aluminum house wiring and doing our own work. Have used it on some smaller projects and am now ready to tackle all of the aluminum/copper connections in the house. Have not had a single failure yet with any of the components. Easy to install and they don’t use much more space in the boxes than wire nuts.
Heads up that if you plan to use the torque method for tightening the screws (recommended) you will need a #5 slot bit and they are almost impossible to find. I ended up using my bench grinder the make one. A square or torx recess screw would be much better.

Best solution that I am aware of for transitioning from aluminum wire to copper wire and not worry about the two metals different expansion and contraction rates.

Alumiconn electrical connectors were just the right items to join aluminum to copper wiring.
best of all, the shipping was free and came right to my house within a few days.

Rated 5.0 out of 5.0 by vbwood The less expansive way to make approved Alum wire connections
The connector is well made, and easy to use. Size is a little larger then I'd like.

Rated 5.0 out of 5.0 by B5G Excellent for aluminum to copper
Significantly cheaper than other options
Easy to install
Similar size to purple wire nuts
Cost of torque screwdriver (but worth it!)
When we bought our house, we were told that it had been pigtailed for Al-Cu. I quickly discovered that only about 50% of the house had been done. (And the previous owners had been ripped off by the electrician. I have the documentation to prove it.) I started doing research because I hate wire nuts, and the Cop-Alum solution is very, very expensive. I found these on the site for the Consumer Product Safety Commission. They no longer recommend wire nuts. They recommend these or the very expensive Cop-Alum.
The instructions contain steps for using a torque screwdriver, or a regular screwdriver. I decided to go for the torque specs. I am going to do my entire house, so it was worth the $200. Just make sure you get one with a calibration certificate.
