Q: My little boy is just getting interested in these blocks. They are too cute! He's learning to manipulate the block in his hands. The little things inside the blocks are adorable. Some spin, some twirl, some rock. A definate upgrade from the standard wooden blocks.

A: Positive
****
Q: An exellent study of the German Airforce from the fall of Sevastopol in the Crimea to its failure at Stalingrad. Very well written, with a clear analysis of the events. Well worth the money and it belongs in every major collection on World War II's Eastern Front.

A: Positive
****
Q: My original charger lost a battle with salt water, which turned it into a discharger. The replacement is exactly the same as the original, except the replacement works! My favorite pocket camera is back in business.
