I was very happy with my product I absolutely love it!!! And it was brand new at a very reasonable price. Gonna continue my shopping on amazon.

Just "assembled" the bat cave for my 5 year old. Pathetic construction and workmanship -- half of the gimmics don't work. Another pile of injection-molded plastic parts and stickers that I get to assemble -- what is this thing -- $4 of raw materials + $2 of shipping + $10 of marketing? Garbage. Shame on you Mattel, the only thing worse is the batman figures with the batarangs that take 30 minutes and a blowtorch to get out of the packaging. This batcave will collapse and die within hours of play, I'm sure of it. GARBAGE!

We have enjoyed all of the Rudy Maxa DVD travel series, especially in BluRay. The programs help when viewed prior to travel and are most enjoyable post-travel. Rudy captures and best of every location. He also enjoys food and beverage, which we appreciate in our household.
