[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]: Very easy company to deal with. I own a cleaning business and my employees love these mops. They pick up great and can reach under just about everything. A little pricey but worth it!
[EX A]: positive

[EX Q]: My family spends most of our summer either at a baseball field or at the beach. We have been using this Coppertone product for years and have been pleased with the results. That all ended with this purchase. When I saw it was cheaper on Amazon than the local store I ordered it. The spray is worthless. We've gotten sunburned both times we used the spray from this order. Threw what was left away and will no longer purchase this product from Amazon. If I could give it zero stars I would.
[EX A]:
negative
