Armor Tools - P7 Armor Tools Self Adjusting Horizontal Dog Clamp (Rating: 1)

I received an Armor Tools Self Adjusting Horizontal Dog Clamp for my birthday and now I'm disappointed with your product this is the second one that has broken in the same place. This is apparently a weak spot in the tool. I have pictures of the broken items if you would like a copy; also the shafts are not even the same size. I must not be the only one in the world having an issue with this item.

I have went to your website and sent a couple of messages, if you feel this is not an issue could you please let me know or if you would like the clamps back please let me know

After a couple months with no response from Armor I just gave up on them
this is the note I sent to Armor
