I just got the Ab Wheel a few days ago in the mail, and can feel results already. The wheel comes with a short instruction paper, but its fairly easy to find more instruction online if you feel the paper isn't enough. It is simple enough to use, just keep your back straight, and roll.
  The first day I tried the Ab Wheel, I did around seven sets of fifteen reps throughout the day. Some background on me is I'm a regular at my gym, started some training with a heavy bag, and am in generally fit shape. So when I did my sets on the first day, I honestly felt nothing on my abs, that is until the next day. My abs ached, I honestly couldn't even do one rep on the wheel. My shoulders were also sore, so expect toned shoulders, arms, and abs. One day has passed, and I'm still feeling sore in my abdominals.
  On the actual wheel itself, it is well built and sturdy. Personally, I felt the ridges were a bit hard on the handle, but I simply put some duct tape around both handles, and now I don't feel a thing. It wasn't necessary, but it certainly helped. I haven't had a problem yet, and the wheel was easy to put together. Just slip the metal bar through both wheels, then slip on the handles on each side of the metal bar.
  I like to do sets each time I walk by the Wheel, so I get a good workout by the end of the day. When classes resume in the fall, I think I'll workout with the Wheel every morning, because I wake up at five, and end up with free time after breakfast. The only thing to be wary of is empty dreams. If you expect to pay ten dollars for the wheel and wake up with a six pack the next day, sorry, this isn't what your looking for. But with good old fashioned hard work and a good diet, expect to see great results soon. Oh and you will definitely feel it in your stomach the next day, your abs will be crying!

  Overall, just make sure to keep your back straight and use the wheel properly, don't work your abs everyday, and you will be very happy with this purchase.
