I think they are very cool. A whole back, my NAPA had a demo of a similar type (house brand) that were pretty cool. They surprisingly had great clamping power. I cannot speak for Hazet though.

Those look to be similar to my old pair of Channel lock 910's. I actually like that pair better than the std jaw vise grips. it's too bad Channelock discontinued them.

I'm fairly certain those Hazet Locking Grip pliers are simply re-branded C.H. Hanson Lockjaw pliers. If so then they're made in Taiwan. Facom has those same pliers re-branded as the Facom 580.6, 580.10, and 582.7 models.
There are good things and bad things about the design.
The plier handle open up very wide which may actually make them more difficult than a regular pair of vise grips to actually use with one hand.
The way the pliers lock isn't as secure as a regular pair of vise grips. At one point I saw a video showing a comparison of the clamping strength of the Lockjaw pliers compared to a regular pair of locking pliers. Both plier types were locked on to a bolt head that was either thread locked or welded. A cheater bar was placed on both pliers and the bolt head twisted. The regular locking pliers twisted the bolt head. The Lockjaw pliers slipped loose. I can't seem to find the video now. It might have been done by a sales rep for either the Vise-Grip brand, or possibly a sales rep for Crescent showing their locking pliers. If you want locking pliers to break loose a corroded bolt, the self-adjusting ones might not be the best choice.
The self adjusting feature can also cause some problems. If you're trying to pull two stiff but not necessarily flat pieces together, such as a couple pieces of sheet metal for welding or riveting, the locking mechanism may lock before the pieces are completely pulled together. The clamping force is adjustable which can alleviate part of the problem, but not all. If you use a pair of regular pliers to pull the pieces together, and then use the Lockjaw pliers to clamp the pieces, the Lockjaw pliers can be convenient for long welds were you don't want to adjust a dozen pairs of vise-grips.
I don't want to be completely negative about the self adjusting pliers. They're very useful for some jobs, but they're not a complete replacement for regular locking pliers.
I think these may be the patents for that type of locking plier. The inventors are listed as Daniel L. Poole, and Robert N. Poole, and the patent is assigned to Newell Rubbermaid Inc. Does anybody know if C. H. Hanson is owned by Newell Rubbermaid? I know Hanson is listed as one of the brands on the Irwin Tools website, and the Irwin Industrial Tool Company has a trademark for Hanson, but C. H. Hanson seams to be a separate trademark owned by the C. H. Hanson Corporation.
The patents.

Sorry if I went on to long.

So far am very happy with them.

Definitely.
It isn't, and the Hanson brand owned by Newell Rubbermaid and managed under the Irwin name was originally the Henry L. Hanson Company of Worcester, MA.
Surprisingly, though, your patent numbers are correct, so I don't understand why Newell Rubbermaid was the original assignee of the Poole patent or how it came to be on a tool made by C.H. Hanson - a competitor.

This is my only issue with them. I LOVE these pliers for typical use. But, when you try to clamp anything flexible, they lock before the pieces come tight.
They won't 100% replace regular locking pliers, but they are one of those gimmicky tools that I actually enjoy using!
Si.
Oh much thanks for sharing pictures, Monte. ( i need buy this tool)
V!
no coo on the tool/package...
