I recently found all except the Endor set, which is the one I really wanted.
1) Death Star set - Death Star Trooper is the same mold as the original. The Mouse Droid is large but it has a "pull-back" feature. It doesn't work very well. The Interrigator Droid is huge as well. Is that to make us not notice how huge the Mouse Droid is? The Stormtrooper belt is cool but if you put a blaster in the holster, the figure can't lower it's arm because the blaster is too big.
2) Hoth set - Hoth Rebel Soldier is original's head on Hoth Luke's body w/ beard painted black. The backpack doesn't even fit on the figure. It comes with a cartoonish looking mini-tank.
3) Arena set - Red Droid is cool. It's the same mold as the POTJ Security Droid and Saga Battle Droid. Weak plastic. The Handcuffs are from the Bespin Capture Han. The extra lightsaberes are cool. The cloak is cool except the hood is sewn down.
Everything is made from the cheap rubbery plastic. They're worth getting just for the extra figures, but don't expect too much from them.
