Certification Kits note

So I was just reading the CertificationKits ASA lab guide/study guide and honestly, I like it. Its straight to the point and looks like a good supplement to your ASA studies. I have to assume that their other guides are of similar quality. For negatives, they use the locked ebooks, so i'm sure it wont be easy to use on multiple devices. But its something to consider.

@alan2308 - I agree that ebay can be a bit hit and miss. My previous company also offloaded some 'questionable' cisco gear on there and I would have hated to be the buyer. I'm sure it's worth a little extra $$ to not have to worry about the hassle of dealing with any problems and taking time away from the end goal....studying.
@SephStorm - thanks for the info about the study & lab guides. I will definitely need extra material when I get around to CCNA in WGU.
