I shamelessly use the site all the time. Elsevier is way too expensive for what it offers. With the way I read, I would have to pay them several thousand dollars each year. This is tax money, so no, thank you, that money can be put to a better use.
The whole system is really outrageous considering they practically sell slave labor - somebody writes those articles, somebody reviews them and edits, somebody prepares issues to go live all for free while those guys just collect cash (yeah, and keep the servers alive - they haven't figured out how to do completely nothing and still get the money yet).
