Yes, they're better than a typical handibox collar like Jumper posted because they fit better over the single gang hole in the surface.

I buy that particular box with the single gang knock out by the caseload. I work in schools alot. They are very handy for add ons. I was supposed to put in two today matter of fact, but instead I am down for the count while I put in a new water pump into my Express van.

Those box extensions that fit over single gang mud rings work great for whipping out for appliances.

I've also always called them extension boxes, and the 1-gang ones are extension handy boxes.
Added: You might consider washers for the 6-32s that hold them onto the existing box or ring. The T-shaped slots are kinda big.
I've used them, too. Especially handy for wiring updating in existing commercial-kitchen Ansul-type systems.

I have a question about box extenders, so instead of a new thread I will ask here

We call them box extenders too. My question is: How many can you add? This morning I opened a 4x4 box with an extension while troubleshooting a light. It is a fairly new install by a contractor. It was surface mounted about 18' from the floor and so full I couldn't get the wires back in to the box. I added another extension. I shouldn't even mention the conduit fill........

There is a picture floating around here somewhere. Atleast I think I saw it here. It was in a commercial/industrial basement looking area. Was probably atleast a foot and a half worth of box extenders. Kid you not. Was pretty funny but scary as well.

Here's a picture that was in an EC&M article back in January 1, 2004 that I wrote and there are more around with many more rings.
