Has anyone who owns/uses the Sir Toll MB spring compressor had any problems with it? I purchased one last July ($600!!) and have used it no more than a dozen times when I had a problem last week. Replacing springs and struts last week, got the left side completed, started on the right and the "compressing rod" would not compress spring enough to get old spring out. The threaded center rod came through the top while in the compressing mode but would not compress enough to get old spring out. Talked with Oliver @ Sir Tools and he was less than helpful, stating that "We have had zero failures on that tool". Just curious, has anyone else had a problem with this tool?
