This is the most complete review book that I have come across. Granted, it doesn't cover the depth of information that the others do, but it is a good review of the most important topics. It is also helpful immensely for test reviews during the basic sciences portion of med. school.

I think it could be a great tool for learning, but there are still a lot of bugs and improvements to be made. I haven't gotten too deep into it yet, but so far, I've noticed some troubles with note recognition. This become most obvious on slides, where it can't seem to identify the notes correctly at all, This becomes very frustrating, as you have to simply give up and move on to something else. Also, they should add 5-string bass support. I've played bass for many years, and actually got this to learn guitar, but hey, why not improve my bass skills? Still, it occasionally gets confusing using an interface designed for a 4-string. The option for a 5-string interface would be a nice, welcome addition. Still, a lot of good stuff here, really good stuff, very helpful for learning and holding your hand through learning. Hopefully an update will arrive to fix the bugs.

This is a great product; I live in Maui, Hawaii and I first found this product at Wal-Mart for the same price I paid through the website. I liked it so much because it doesn't go on greasy and has a pleasant scent, almost like you were applying regular lotion. The only negative on this product is that it only lasts about 2 hours, so if you're going hiking or any other place where you'll be for a longer period of time, either bring the product with you for re-application or use the regular spray OFF product.
