These work great as ankle cuffs but you could also use them for your wrists if they are on the larger side. This product will work for anyone whose ankles are 12 inches or less in circumference. I would say that these are great for both beginners and advanced users alike because they are both beautiful and strong.

I love the design of these. I got them to match the wrist cuffs that I already bought, so I knew what to expect in quality and was not disappointed in any capacity. I feel that these will last just as long as the wrist cuffs as I have seen no real wear or tear on either set. 

These have a faint leather scent when you open them but I've never seen someone complain about the lovely smell of leather. These are nice and smooth on the outside. However, the inside, like the wrist cuffs, is unfinished so if you don't like the rough feel of unfinished leather, you may want to look for something that has a nice soft lining. But if you like the rough feel, then these are great. 
They fit me well; I can go between two holes depending on how tight I want them to fit. I would say that they should be a good fit for most people; I know that I am on the outer limits of the size range. My ankles are right around 11.5 inches in circumference but I still feel secure in these.

These have worked great for me. I just bought some clips and now I can clip them onto anything I want, such as my bed frame, each other, or my wrists. These have fully met my expectations for what I wanted when I bought these. Of course they don't lock on but this is not a requirement for me.

I store these in my toy box next to each other and sometimes clipped together for ease of retrieval. I feel as though they are easy to take care of since we don't use them in a manner where they would get dirty. But if you must wash these, make sure that you don't get them wet and only dab them off with a damp cloth if its absolutely necessary. If it's a more extreme problem, then you should break out the leather cleaner so that you don't accidentally ruin them.
