Sometimes I also use them to sorta guide my studying path along with the exam blueprint.
Overall, if I didn't have a free Safari Books online account, I probably wouldn't purchase any of them, but the more resources you have at your disposal the better.
I've been using them since they were available as a PDF document on the CD of the Cisco Press Flash Card and Exam Packs -- and have always found them useful.
The prices are reasonable for the current downloadable Quick Reference Sheets on the Cisco Press web site (Adobe Digital Editions DRM) -- and they are available on Safari (downloadable as PDF, MOBI, or ePub formats with your Safari tokens -- with watermark and "branding" with your name as a footnote on each page).
Quality is ok - base concepts are laid out.
Can recommend only as a side dish
