IronFactory EX-70 Drillhorn
BenZonah: Awesomely done. This con is great. Fairly easy transformation, lots of accessories and a combiner leg shell. Quality seems good. Paint job is nice. My copy seems nice and tight and is very poseable.

Thanks to ShowZ for getting me a piece that was missing from this set.
IronFactory EX-69 Killbison
BenZonah: Iron Factory really messed this one up. Overall it looks good. Very posable, lots of accessories, painted nicely seems tight and not loose.

However, I did read the instructions and there is no way to transform the legs in bot mode to alt mode without scraping the white paint on his legs. There should be something that allows for clearance but there is none. This is a major design flaw. I have tried multiple methods and directions and the clearance just isn't there.

My copy also had a problem with the open weapon holding hands. There was some extra plastic blocking the weapons from being inserted that needed to be cut away.
IronFactory EX-69 Killbison
CDanz: I'm out on this set. Its not even QC though I've had issues with this guy on that, mainly flimsy plastic, but the design is just bad. Drillhorn's treads basically have to be removed to transform hm and Killbison's shoulders can barely articulate.

Most I can say are the breast beasts are pretty fun.
BenZonah: You're right about the treads. If you do it the way in the instructions, you will scratch the paint. This is a design flaw, not a QC issue. Iron Factory is a sub-par company it seems.
IronFactory EX-65 Leozack
BenZonah: One of the better bots in this team. Iron Factory kinda redeemed themselves with this one. It has a good transformation for all modes. Like the others, it's very poseable.

Spear comes with swappable points. Has some of the ultimate weapon parts. Combiner head looks cool. Combined mode isn't cartoon accurate with the cockpit facing out, but looks cool nonetheless.
IronFactory EX-66 Guyhawk
BenZonah: Overall, a decent figure. My only gripe is how they put a ratchet type elbow when in combiner mode. It doesn't feel that strong and seems like it could break with repeated use as the force from moving it puts pressure on the peg. I can see it bending back.

Aside from that, it's a good set.  Poses well, jet mode looks good. The headsculpt is good. Breast animal is good and the combiner weapon parts are good. The combiner has articulated fingers which is a nice touch.
IronFactory EX-67 Hellbat
BenZonah: A decent bot. Like the other arm, I don't like the method of including the plastic ratcheting elbow that is used as the lower part of the double elbow. It feels like it's going to eventually break. Other than that, Hellbat transforms decently into all three modes. I like how the plane has landing gear, which is more than a certain other company would do. The color scheme is very nice on him. The combiner hand has articulated fingers, which is a real nice touch. The breast plates are a good compromise by including three (transforming animal, static breast plate, and a static gun.), giving you the option to customize the look of the figure.

Without having Death Cobra, this is a decent set overall. Some design flaws and QC issues throughout the set. The emphasis is on combined mode, which seems to work well. I give the set as a whole 4/5.
DNA Design DK-61 Upgrade Kits for Legacy United Vector Prime
BenZonah: Decent kit with some flaws. The Vector Prime figure is plagued by bad QC and is a floppy mess, so this kit goes on top of a bad figure, which DNA has no control over. It makes him looks much better in bot mode. My copy of the figure has bad QC on the wings, so the heavier wings from this kit end up making the wings a floppy mess. Not the kit's fault, just bad figure QC.

The upgrade requires some glue for two pieces and requires some pieces to be taken off during transformation. Both those things knock it down 1 star. Still a decent quality kit. Better than the actual figure I'd say.
Dr.wu & Mechanic Toys MS-37 Giant Axe Broadside
BenZonah: Seems like a sturdy bot. The transformation into all three modes is very intuitive and easy. The joints all seem good and not loose. He can pose easy and looks good. A worthy purchase.
Dr.Wu DW-Coronation Kit for Starscream
BenZonah: Good set. Cape is not very secure and it falls off. The way it goes on limits the arm articulation. The Starscream figure itself has problems with the null rays falling off and this set exacerbates this defect. So you gotta be a little careful moving it around. The throne is nice and Starscream can sit on it without any issue, though the cape needs to be removed.
Star Toy ST-02 Tracks
BenZonah: The car and flight mode look fantastic. I'm not really feeling it for the bot mode. It looks a bit weird for my tastes.
