JediTricks, I opened Voyager Megs earlier this afternoon. Here are my thoughts:
I really like him. He is not a perfect toy by any means, but for the Voyager pricepoint, he really works. The thing I like most about him (and this is just something I like personally) is his green and silver fading. The coloring on him makes his details really stand out.
As far as transformation, it was fairly easy. I had a little bit of trouble getting him back into tank mode because a couple of the tabs on his legs were tough to line up, but it wasn't time consuming at all.
There is some kibble on his back when you have him in robot mode. The wings from tank mode fold back, so they are exposed back there when you have him standing up. That is only noticable when you have him posed to the side though, so its not an issue.
For a Voyager toy, his proportions are very good, and his gimmicks don't really get in the way. This helps to make for better posing as well.
Overall I would give it an 8 out of 10.
And I had a nice haul today. Picked up Mixmaster and Human Alliance Bumblebee.
