rerun119 the arms have gas spring so i can push down to get in position or push up to get out the way when finished with it, only adjusted a screw on the spring once to get the setting right for the spring. the second one i use for my bed its a common cheap arm they sell very similar kinds many places including amazon
see just now the new mounts that kirro made that realcucumer mentioned, which look like decent solutions. The old neck strap was just a bad idea imo
