I have had an oppertunity to try out the Packer and it works very well. The only comment I have is that it is a bit loose when attempting to close down on the hook. To clarify the notches that hold the hook do not line up when attempting to clamp around the hook. That may be a small fault that is of no concequence or not fixable.
I want to complement you on the speedy delivery of the Packer. I got it the next day.
