My job requires long hours and intense training mixed in. I decided to try MasterBrain 3 weeks ago and I have had great results. First is my sleep, living in the city we have a lot of loud noises that tended to wake me up but since MasterBrain I have been staying asleep longer. My job requires me to be on a computer for long hours and I struggled to stay concentrated. About a week of taking MasterBrain I had noticed I had been making more calls and getting more done at work. Love this product and will continue to use it.

One of the worst product lines I ever purchased, another has been celebrity trying to cash in on past fame, touting an inferior product that actually has no benefits. I would rate this product zero.

I used this to make a pair of "custom fit" ear buds. Normally I have trouble keeping them positioned just right. Used the Sugru as directed to form fit them to my ear canal and they stay in place perfectly.

I would highly recommend this book. I ended up going through it slowly, got busy with work, then used it to cram 2 weeks before and I did fairly well. In short, I think it will work for you whether you're cramming or taking your time. I certainly did better than I would have without the prep book and any part of being unprepared was by my procrastination. Plus, the writing is fun and conversational, which helps breaks up the frustration when you don't remember the math you feel like you should remember!
