Seller was fast and easy to speak too, answered questions right away. I found that the shipping was also very fast and packaging was perfect. Everything arrived safely. The book was actually everything that I wanted and needed and I am hoping it will help me pass my boards (Will update once I know). I think the price is a bit high but since there is no other choices and limited for test taking for exam study material for Bone Density for the ARRT, I think this will do nicely! Highly recommend!
