I found this book often lacks detailed explaination and statement, which makes it difficult to clearly and smoothly understand. Unlike some excellent textbooks by which you can easily make a progress every day, I often need to figure out by myself what here means, or why it is like that. Now I use other textbooks, and feel far better. Is this product review negative?

Review: I thought the mangroomer would be a great thing for my husband's hairy back, however, once he tried it, I changed my mind! It is very light-weight, which is nice, but it does not give a close shave and the other reviewers are correct in saying that you'd need a 3-way mirror to shave it correctly and thoroughly. My husband gave it a try and had trouble with it staying on, almost like it sucked the battery juices right out. Then I gave it a try and thought a disposable razor would be much more efficient. It did not give a close shave and it clogged up quickly! We both agree that $40 is much too high for this product. Don't waste your time people with hairy bodies! Use Nair or a razor - much more efficient! Save the $40 for something more exciting and useful like a waxing!! Is this product review negative?

Don't they test these things before packaging them?? I took the two that didn't work back and don't plan on buying another cooper product. Is this product review negative?

As a huge fan of the first 2 Mercyless albums, "Abject Offerings" and "Coloured Funeral", I was not expecting them to change directions musically. What Max Otero has done here is pretty much what that other dumbbell named Max has done. What the heck is it with frontmen named Max?? Why do they start out awesome and then go lame? This CD is a complete failure. No technical riffs, no intense drumming no song writing no arpeggios nothing! Mercyless have become just another B.S. Ozzfest, Korn, Slipknot mallcore band. Such a disappointment! If you have listened to "Abject offerings" then you know what I am talking about. Its a shame to see such a great band regress into complete talentless musical crud. Mercyless need to wake up and quit wasting their time and talent creating garbage alternative poser metal and return to their Technical Death roots. Is this product review negative?
