[EX Q]: Reading this book felt like a puzzle set out before me. I had all the pieces early on but didnt know how they fit together. The author takes your hand and leads you down an amazing, glorious path, explaining the need for each piece. The end result? A master piece.
[EX A]: positive

[EX Q]: This band looks really nice with my rose gold Apple watch and I love the protective cover as I work with my hands a lot and worry about damaging my watch. It is a little bulkier but not bothersome and can be removed if not wanted. Swift delivery and arrived as promised. I have very small wrists and this band still fits nicely.
[EX A]:
positive
