We all know about cases of rubber tires cracking and falling off. This is an immensely disappointing moment for any Transformers fan but that's a discussion for another thread. I'm more interested in the toys (particularly those that have come along since the late 1990s) that have sections of flexible/rubberized plastic. I recently pulled out Transmetal2 Megatron (Ultra Class dragon) and Transmetal2 Dinobot (Deluxe) and found that their flexible plastic sections have seemingly not deteriorated at all...which, at least in the case of that awesome Megatron dragon, great news. There are quite a few guys in my collection that use this material...so far, I have had absolutely no problems. Generations Rhinox is one I'm keeping an eye on but after 2+ years of regular handling, he's still perfect. Nevertheless, every time I see a review on a newer toy with a flexible section, the reviewer casts doubt on the longevity of this material...what is this based on? Have you guys had problems? If so, which figures have failed? Is this all based on bitter memories of G1 Shockwave's rubber hose? Are people extrapolating based on their experience with RiD (2000) tires falling off? Any thoughts are welcome. Transmetal 2 Dinobot, supple plastic or not, is still a very weird figure.
