Great for ice walks on frozen canyon floors or for glacier travel. Obviously not for ice climbing because they can't be attached rigidly to your boots.
Flexibility makes them comfortable on almost any winter boot, and you can almost walk normally in them.
One nice extra is that the ones I bought came with antibot plates and a crampon bag. Nothing more to buy.
Remember to dry them off after use, and when putting them away for summer storage, dab them with oil to prevent rust.

Considering these are one of the cheapest crampons on the market, I am very happy with my set. I have crossed glaciers, climbed ice walls and mixed rock/ice, so all in all, very versatile.
As a downside, the metal frame digs into my boots and have cut little holes in the rubber toe caps of my La Sportiva from the friction. I would recommend bending the metal frame out a touch to avoid this.

I bought these during a promotional sale at EMS. EMS by the way has the cheapest price on these even though it isn't listed here. They go for $99 I think on EMS.com
The only reason these get 4.5 stars instead of 5 is that if you pack them incorrectly, they are literally almost impossible to adjust for size when putting them back on your boots.
It has the typical peg adjusting system. In order to fit them into the pack they come in, they must be adjusted to a smaller size. When doing this, make sure the metal piece that slides and the peg goes into, goes UNDER the antibot plate, not over it. If it goes over it, it puts the metal at a weird angle, and makes it VERY hard to take the peg out to adjust size.
When using these I found that they stay very stable and tight on the boots, no slipping. They bite into the ice very well, and had great stability even when trekking on rocks and ice mix.
