Really great stand actually. It does work with my 1/100 kits, holds them up well and is really easy to use compared to the older action bases. There are screws in the build, but just follow the instructions given and you should be fine, you don't need a screwdriver because Bandai molded these hexagonal keys . It may not hold up really big, heavy models up very high, but it will at least hold them. It's not prone to breaking like other clear ACB's out there because Bandai smartened up and decided to make the plastic thicker this time giving it more strength and stability. I don't know if I would heartily say it'll work for every 1/100, but it will work with the majority of them, and certainly more fun to pose models with. However the center hold on the base plate of the stand is really loose for some reason, but the other holes are nice and tight like they should be, so the center hole must've been screwed up at the factory because it is so loose to the point where the base plate will drop off of the stand arm if you pick it up without supporting the bottom of the base plate. Despite that the rest of the stand is really great, except for the fact that the adapters included are only for peg holes, there are no "cradle" style adapters like those that would've come with the ACB 1 or ACB 5. But I think this stand is more fun to use, quicker to build, and stronger to a degree than the other actions bases out there. I highly recommend it for 1/144 and also 1/100 kits, but try not to use it with extremely heavy or large models as that could weaken the base. I've had my RG Hi Nu with the EffectsWIngs hyper mega launcher on the stand on my shelf for about a month, and the base has not loosened up or become broken because of the H-Nu's weight. Give this base a chance, it's really quite good!

This could be good, but you have to tighten the bolts so much to hold up a MG lile its designed to do. And if you do that, the plastic tools arent strong enough to loosen the bolt without breaking.
