[EX Q]: 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!
[EX A]: Negative

[EX Q]: Now my daughter will not stop aggravating me because we cannot download the pictures off of the dran thing and wants a new camera, so now, I have not only wasted my money, but I have to buy her a more expensive camera that will work that she will break or lose.Thanks so much Vivitar!
[EX A]: Negative

[EX Q]: I noticed a few reviews complaining about their extension cords breaking down after just few months of usage, so I decided to let you all know that after nearly THREE years of use, mine works just as good as it did on day 1. It was cheap, does what it's supposed to, and hasn't failed me yet. Buy with confidence!

Positive
