Hello of DLD and all. Today during my workout length broke in my part of the chamber LM, when I was in the middle of the chamber. Nothing had happened to me. I used a correctly LM and do not understand.. I wanted to tighten the chambers and then it happened. I note that my post is not intended to criticize the DLD or LM. I have respect for every member of the forum and I thing the LM is a very good idea. DLD, what do you think?
