Love the idea, mine was defective.
Absolutely loved this item and the idea of it, but mine was defective when it came in. Elmo would not fully pop out when it was supposed to and had to be pryed out. Tried multiple times before deciding to return. A family member ordered one as well and theirs was perfect!

Revenge for a fallen emperor, redemption for a fallen warrior
Format: Kindle
The crimson empire saga is the story of kir kanos, last of emperor Palpatine's crimson clad imperial guardsmen. It is a story of revenge and redemption, as over the course of the trilogy Kanos grows and changes in ways he'd never have expected. I did especially like his changing relationship with Mirith Sinn, and how her arc is a fitting mirror to his own. I also liked the villain of the first series. Jax, and I wish he had stuck around for the rest of the trilogy. The rest of the villains throughout the trilogy are far less memorable than jax, but I suppose that's the problem when you make sequel to whats unseemly a self contained story. Of the three series contained here, the first series is by far the best. It's quite self contained, and any knowledge of the universe at the time is explained quite well. It's also the simplest, Kanos wants Jax dead, and Jax wants Kanos dead. The second series is abit of a mess, with an overly complicated plot and a good deal of unseemly wasted page count on the random side characters that don't advance anything. In particular I'm thinking of the hutt character, as well as the mystery hooded figure who doesn't actually come into play at any point in the saga. Perhaps he comes into play in some later star wars story, but in this it reeks of a dropped plot line. The third and final series is a worthy sequel to the first although the scenes with Han solo also seem unnecessary. I did like the ending of the saga, even though I would have referred a bit of a more definitive ending in terms of certain character relationships. The art of the saga get progressively better with each series. In the first series it's still reasonable good, but some of the faces and body proportions are bit weak. By the third it's really good if standard comic art. The fight scenes are well done throughout, and the ship battles are a great to see. In conclusion, I would recommend this to anyone who likes a good revenge story. Don't worry about the context of this in the greater star wars saga, the most pertinent information is explained well enough, in my opinion. As long you have seen the star wars movies and remember who the emperor is, your good.

A must read
Format: Kindle
This series is a must read if you love Star Wars post Endor. The galaxy is still in a struggle to see who is on top. With many a individual falling through the cracks in galactic society.
