Okay so after tinkering around with this piece awhile, I did get it to light up. However the connection is not solid at all, I have to manually push him back some to make it light upm in its normal position connected to the base the connection is weak and the lights flicker.
Now light up features to me are just perks. I never buy a piece BECAUSE they light up, most of the time I make sure it works, and they never get turned on again. I will say in my personal opinion if you are buying this BECAUSE of the light up, or the light up was keeping you from cancelling you might be disappointed.
Again this is just my 2 cents, but the power of the light is really bad. I just got my HT War Machine in this week, and his chest light is so bright, it actually is hard to look at directly. You can see it very bright even in daylight. I had hopes this piece would be extremely bright also, but the brightness is an incredible letdown. I'm looking at it right now, power turned on in a lit room and I can barely tell it's a light up function.
Also for some reason I pictured the gems as being transluscent plastic, or god forbid smoked glass orbs. What it looks like they did was make the gems out of clear (whatever material) and paint over them with paint. Its thin enough paint to where some light shines through, but I bet the paint is blocking a lot out. I personally would have paid another $15-$20 for the gems to haave been something like glass to where they had some depth, shine and reflection.
But alas, the review is not all doom and gloom, while I still think the face looks like a silly pig, the overall presence of this piece is really impressive. MD is stunning, and the exclusive head is wonderful. I think for the amount you paid, you get your money's worth. I do not feel like I overpaid for this piece. Scales I could honestly give two craps about, I don't care if a 1/5 Spider-Man is next to a 1/4 Venom or something, I buy what I think looks cool, so with that said, I think the scale is just fine. If this piece had been in line with the surfer comiquette, it would look nice Im sure, but the price tag would probably have been $499 and probably would have never sold out.
So all in all I think this is a pretty cool set, aside from the broken cap shield.
Hope that helps!
