Hi,I think you should get the vendor to replace them. If they are loose and wiggly then very time you try to cut something the twig will end up wedged between the blades and get crushed, not cut (which isn't good).

We hear a lot of horror stories about the demise of somebodys trees, but poisoning like this is a first for me. I hope you didn't loose anything too valuable.
