You say no one watches these compared to your talking head videos. I just want you to know that they are still important and we appreciate the time and effort you put into making them.

Just discovered Eli. It's actually hilarious how good Eli is at explaining concepts and then providing real world implementation compared to some of the people I've watched for comptia stuff.

I'm a systems and applications admin and this explanation of the osi layer is actually more useful/helpful then the way I learned it from a book.

Miss these classes, I'm always able to understand your lessons better than others

i can't believe that i can learn all these cool things on youtube, pause if i need to, take a moment to absorb, take notes or whatever .It is awesome.Thank you

Literally took a break from an actual Cisco training just to see Eli explain the information in his own way. Definitely appreciated as humor keeps you engaged with the actual information as well real life scenarios.

I've struggled for the past 2 weeks in understanding the OSI model. This video made it make sense. Thank you dude.

Amazing stuff, Eli. The story telling incorporated with the practicality of the OSI model cannot be overvalued.

I've seen this model like any IT person a million times & this is indeed one of the most well explained I've ran across! I try teaching my children IT & I will def be sharing this. Thanks!!

Best IT channel on YouTube. Hands down

[ManLikeKitch]

I missed these classes so much. It feels like it's been years. Thanks, Eli.

You’re an awesome teacher. Currently studying for network+… I find your videos explain concepts better than my coursework.

[limitless]

To me the OSI Model will always have a special place in my heart.
Was the first model that demistified the iner guts and iner workings of Networking...
Great video thanks!

Only few people care about your tech videos, because they go obsolete after a while, but your analytic talking head videos are gold to your international audience

[mahendragurlhosur]

Wow.. after a long time I am back again to learn & Here He is back again to Teach ... Nice to see you back & You still look the same Young

[elviorion]

Studying for a test I'm scheduled to take later today and of all the studying I've done your video was by far the easiest to understand. Watched this one, and your 13 year old one and they are just so easy and full of information that's actually useful. Wish I'd have found you sooner!

[georgerafa]

Eli I'm just a newbie in my IT journey but I've been going crazy watching guys like Michael Meyers and Prof Messer that just dont make things relatable or fun like you do. Thank you for what you do amigo. God bless

[miszlo]

I am not sure why the way you explain information it makes sense. Thank you for these videos!

[ericslusarz]

About to take the Network+ and this was helpful well beyond the test and cert. Thanks for your time and unique style.

I resubbed because I saw you posting these videos again. Will be able to watch them later. I find it really easy to learn from your teaching style, and hope you continue making educational format videos.
