I own the mini-bots and I get the impression that they are better made. I own a broken G1 Bumper and Pipes, and I used to own the G2 minibots. The G1 Walmart reissues seem to be made of a better quality plastic and appears to be more sturdy. Unfortunately, I don't own any of the originals to really confirm what is better quality. I feel the Walmart reissue of Devastator was better made than the G2 Devastator, but maybe it's because my G2 Devastator is older and I was more rough on it as a child? As for the cassettes and the seekers I get the impression that the originals and the reissues are the same in quality. What do people think of the Walmart reissues compared to the original? Are some of them of better quality than the original?
