Seems like I noticed this thread late.

I have such a eyepiece.
My findings are the same as drjaxon.

At max magnification, there is vignetting unless one 'eyeballs' left and right.
The eyepiece optic also looses sharpness on the periphery, so the best way to use it is to use the the center or near center for focusing.
Sometimes, the rubbing on the body and eyepiece during walking can turn the eyepiece from the max magnification position, but no big deal, just turn it back.

For the cheap price I got it, I think its fine, and the most magnification out there.
Anything with higher magnification would severely vignette and pose a problem of getting proper FOV.

At about which magnification the vignetting is not noticeable?

At x1.58 mag.
But there is some at the other mag setting too (1.3x? can't remember the exact mag value)

My own conclusion was that there was no free lunch and the OEM were not 'dummies' when they limited their eyepieces to 1.15x (like the Pentax one)

If you wear glasses, take note: the Pentax magnifying eyepiece is hard to use when wearing glasses. This might be the "straw that breaks the camel's back" for me to finally get contacts or Lasik...
