This is a 6 x 4.5 x 0.5 inch book that is basically the federal rules with SOME objections. So far the description doesnt sound so bad right? But then throw in that this tiny little booklet is $35.00 bucks. If you buy this, and some of you will, you will be shocked at how tiny this book is with large print running you 35 bucks. I got a required book on the federal rules and a book on objections that total $70.00 and both on their own are worth more than this. Get something else if you can. The books I purchased instead of this are below.[...]
