I bought one about 9 years ago that looks like the Stinger one. Got it on ebay so not 100% sure.
It was a heavy white piece with a door. All the posts had to be tapped and all door holes opened and tapped too.
Took a friend that was a bodyman about a week of after work massaging.

The PG one came out about a year later and I thought boy if only I had waited. Then all the reviews of them came out and it really sounds like junk.

My buddy was able to make that one I bought look really nice especially after shooting it with Organisol. The door wasn't fully closed when that picture was taken.
