Rated 5.0 out of 5.0 by Tyrebyter The safe alternative
Though the National Electrical Code permits Special wire nuts on aluminum wiring the Consumer Product Safety Commision says they should be considered temporary at best. The CPSC recommends Alumicons or Copalum connectors, and the Copalum requires a special crimper that can only be rented by electricians certified to install that product. These Alumicon connectors are easy to use and can fit in most boxes There are instruction for installing with a torque-limiting screwdriver or an ordinary flat blade screwdriver. I replaced most of my home's wiring with copper, but that I couldn't reach, I pigtailed with Alumicons. Now I sleep better.

Rated 4.0 out of 5.0 by dpi Useful and practical wire connector
I prefer using this product to connect wires rather than with wire nuts and tape. Wires are held securely by the screw terminals and very unlikely to come loose, unlike what can happen with wire nuts. This product is especially useful because of the often increased difficulty for me when connecting 3 wires with wire nuts. However they seem quite expensive at over $3 each.

This product is one of only a few listed al/cu connectors. It also does cu/cu, and al/al. I don't know why they have to be so rediculously expensive, but given the cost of an electrician, they are a small percentage of the total project cost. I'm a licensed electrician and have a couple clients with electric heat and aluminum building wiring. When the old connections fail, it's almost always because of poor workmanship, not the old connectors, but these are trying to legislate against incompetence. They reqauire a torque screwdriver for proper application, but have an alternate method of torquing that doesn't reqauire a calibrated screwdriver. Theypre quite bulky and make a single gang box very tight. I use the calibrated screwdriver. KUDOS to Home Depot for having these on line. The product is great, the cost rediculous.

Rated 4.0 out of 5.0 by BigG A less expensive option than rewiring the house
I started with a small order of these and ended up with the 100 count bag. They worked and are one of the only options for pig tailing aluminum house wire to copper only switches and plugs. I purchased a home in which all switches and plugs had cu or copper only stamped on them. The aluminum house wire was connected to these. (Fire Hazard). After much investigation I found out that you should install copper pig tails because most commonly found switches and plugs are copper only. This product is approved for aluminum (AL) to Copper (CU) connections. The wire connectors have anti corrosion gel in them to prevent the aluminum wire from corroding. The only issue I encountered was that the screw terminals were a little soft, make sure you use the right size screwdriver. Also they recommend using a torque screwdriver. The larger bag had optional instructions if you didn't have a torque driver.

Rated 4.0 out of 5.0 by ToolManTim Please give real dimensions in specifications
The dimensions in the specification are rediculous. It wouldn't fit in a box if it was that big.

Rated 5.0 out of 5.0 by MZ The only safe DIY option for aluminum wire remediation
There are only two products approved by the Consumer Products Safety Commission for safe remediation of aluminum branch wiring, and I chose this product because Alumiconn is one of them. Alumiconn connectors are the only option that homeowners can install themselves. The product is easy to install and a little larger than a wire nut. I have installed many of these throughout my home, and have had no issues with them. You simply strip back the insulation 5/16", insert the wire into the connector and tighten the screw to the recommended torque. I also purchased a torque screwdriver to make sure that I installed them correctly. You will need a minimum of 2 connectors for each outlet, and a minimum of 3 for each switch. If you also need to put these on aluminum ground wires in the box or on 3-way switches, you may need as many as 4 or 5 in a box.
Fitting 4 connectors in a box is difficult, but can be done by careful routing and packing of the wires. If there is not enough room, installing a larger remodeling box is not that difficult. One of the other reviews here said to use Ideal In-Sure connectors if you don't have enough room for Alumiconn. Ideal Industries clearly states that In-Sure connectors are not to be used with aluminum wire. Alumiconn connectors are the only safe option. Using In-Sure connectors may increase the chance of a house fire.
