Exactly, there are a couple of videos on YT that cover the RS451, which means they had an embargo on releasing reviews. This is typical.
My disappointment is that their own site wasn’t updated to add the product at the same time when they lifted the embargo. So for example… if you have an embargo to stop any review releases or discussions before Sept 1, your website should update at midnight on Aug 30th or just update on Aug 30th so that your site has the data for 24 hours in place just prior to the embargo being lifted. That way someone hears about it… sees the reviews and can go to the vendor for detailed information.
