I have had nano rings and a weave. I found the nano rings to be the best by far in all areas and look a lot better too. I always opt for Remi Cachet hair and whilst its not the cheapest it is great quality and lasts for ages. I get just under a year out of mine before I have a new set in. I do look after it carefully though, pretty much the same as I do my own hair. My actual hair is pretty long and thick, I only had extensions due to some small but noticeable alopecia patches that made me feel so self conscious. They haven't damaged my hair at all and I think put less strain on my roots than a weft/weave did. they also look better when goring out than my weave did.
I haven't had any other methods but think ill be sticking with nanos for the foreseeable future!
