eurolocs vs microlinks

I used to be an avid user of eurolocs on my clients, and now I won't offer that method anymore.

First of all, the jury's still out on whether the copper corrodes the natural hair.

Secondly, I think that when you crimp that copper shell, rough, sharp edges are formed sometimes and I think it can cut the hair.

Thirdly, the pincher type tool that you use to reopen the shell, I think it may slice hair.

In any case, the breakage that I have seen it cause is unbelieveble.  I have never seen breakage like this from any other method, and I've tried a lot of methods in the last 14 years.
