I have handled quite a few of these (25 - 30).

There are a few different versions , some come with sun shade and flip up covers, others don't.

Some also have the Leupold logo on them.

The quality does vary between them but the ones i brought in were checked over by the seller in China and they are about the best value scopes I have tried.

The objective lens and the illuminated reticle control's on some are different to the the ones on mine and on some the turrets can be reset others can't.
The one's with the logo are pretty goo dcopies whil eth eothers are not as close

I have heard that some can not be reparallaxed because the front ring can't be removed.

The packing on all looks the same.

A few people i know have been caught out on "that site" with sellers sending M3 versions when they won M1 versions.
