Seems like each binocular maker has their own idea of where the eyecup should end in relationship to the length of the eye relief. Some have eyecups extending on the shorter side compared to other manufacturers.
Eye placement varies between the brands I own. I have to place models with eyecups on the short side (in relation to the eye relief) higher up closer to the eyebrows. This method of accommodation was mentioned by Ronh and has been given the name Molcet by other members of this forum.
Aldo,
This kind of thing has been discussed a good bit here. Some people have ways of dealing with that, resting the eyecup on the brow and adjusting the angle of the head to increase the distance from the eye to the eye lens, and gazing "upward" for the view.

Here is a description of the Molcet technique. I bet it will be familiar to you!

It sounds from you description that the 8x Razor may not be in physical contact with your face. If the Molcet method does not work and you do not have physical contact with your face, then I say do not buy the 8x Razor. You need to anchor the binocular to your face in order to get a steady hold. I know some people use a free floating hold, but ......
I would expect to see eye placement inconsistency between manufacturers and even between model lines of a manufacturer when considering the manufacture may be outsourced to different companies. It is surprising to hear about such a big difference between the two Razor models. I briefly looked through a current model once and do not remember any eye placement issues. I think it was the 10x. I am now curious to compare the two models.
I own several Zen-Ray models and I have to hold all of them slightly higher up than some of my other brands. There are other Zen-Ray posts here about posters modifying the Zen-Ray eyecups with winged replacements or rubber washers, etc, to extend the eyecups (but I did not have to do that). Some say they fit perfectly but they may not be a good choice for you. Just like shoes, the perfect fit is different between individuals.
Since you are looking for a high end binocular, then consider a used Nikon EDG I or II (or even watch for a vendor sale). I have the 8X32 and 10X42 and both have a longer eyecup in relationship to the eye relief, allowing perfect placement for me. The placement is consistent between the two models. I think you will also find the optical qualities superior to the new Razor, especially considering the flat field view.
If the size is not a turn-off, check out a used 8.5X42 Swarovski EL WB. They sell for about the same price as the Razor and may provide a superior view. As I recall, the eye placement was similar to the EDG. It is not uncommon to see offers of like new models with original boxes and paperwork. Make sure it is a model imported by Swarovski of N. America to get their famous customer service. You mentioned in the post from last year that you bought a Sightron 8X32 so I am thinking size is not a big issue for the Celestron replacement.
Whatever you get, make sure you have a return option, because the only way you are going to know for sure if they are right for you is to try them for several days.
