About the trainer, he's genuinely interested in making you understand the concepts and the background work of VMWare. The way he explains is into pure layman terms and its very clear no matter what term it is. Networking, Storage, Architecture it sounds so simple now.
About the classes, its a fun learning environment where boredom doesn't even stands close. Everything is so interesting that you want the class to go on like forever. In technical terms, is a high speed download in your brain over over a Fiber optics connection..
From all the learning I've taken from other institutes, I would highly recommend this training. If you are in VMWare and looking forward for proper guidance, this is a sure stop shop where all your queries are answered and all doubts are cleared.
