Chris pretty much nailed the problem with these guys in his review of the TAC version way back in 2014.  The difference in combat effectiveness between the B1 Battle Droid and the Droidekas is ridiculous.  One is a joke, and the other is an almost invincible killing machine.  After we are first introduced to the B1 droids on board the Trade Federation Control ship, Qui-Gon and Obi-Wan roger-rogered a squad of them with almost comical efficiency.  But then a pair of Destroyer droids rolled up, and there was palpable concern in Obi-Wan’s face.  They fought the droids for a few seconds, but quickly made a hasty retreat.  You’d have to think that if the Separatists cancelled the B1 droids and instead used those resources to make 1 destroyer droid for every 25 B1’s, the war would have been very different.  But, I guess, that was all part of the master plan, as the CIS wasn’t supposed to win.

Hasbro has released many destroyer “droideka” droids over the years.  They’re all nearly identical sculpts, with a few variations revolving around paint, accessories, and battle damage.  The reason for this would seem to be that Hasbro pretty much nailed the likeness in the first try.  It’s a great looking figure, and looks just like the character in the films.  The head has the 3 photoreceptor eyes, and swivels up and down (almost like it “nods”).  The “shoulders” and “wrists” are hinged.  There is some movement at the “hips” (where the three legs connect to the ball/body) and the “knees” are hinged.  One other bit of “articulation” is that the spine is made of a bendy plastic, so you can shape it a bit to change up the look very slightly.  All of this articulation, however, doesn’t really amount to much pose variability.  Especially frustrating is the hinged “wrists”, and lack of “elbows” which make it difficult to realistically point the blasters straight ahead.  The knees are loose on my sample, which sometimes can cause the back leg to fold backward.  The head is also a bit loose, so the figure doesn’t easily look straight ahead, but it swivels down so it looks at the ground a lot. 

On major feature missing is the ability of it to roll up in to a wheel.  That definitely would seem like a big ask, but hey, Hasbro is the company that makes Transformers, so someone over there should be able to engineer a Droideka that properly rolls up.  Until that day comes, this will likely never be a definitive figure, but it still works very well in your displays.  This is a great looking droid, but it struggles to accomplish much beyond just standing there.  Better arm articulation would allow for improved canon firing poses, and other joints should be tighter.  But the paint and sculpt are otherwise outstanding.  Despite later releases having some gimmicks or accessories of variable desirability, this figure still holds up well.  Nevertheless, there is there is plenty of room for improvement.  I give it a 6/10.
