You have to do a little extra work by magnetizing the bases of your models, however it is a thousand times better than foam cases. The models don't rub up against anything and taking them in/out is a breeze. I have broken so many models over the years just by trying to take them out of a foam case. This fixes the problem.
It's also far superior in the regards that battle foam is pretty specific to the model. You can fit a specific style of model in a case but not another. The magnet tray lets you put as many in as you can fit no matter the size of the model.
I have Seraphon models (big dinosaurs) and have never been able to carry some of them in a case, which always made it awkward to take on the road. This case has plenty of room because for the really tall models just remove one of the trays before hand.
I only see two negatives with this case. One is you have to build it. Very minor issue but it has the risk of not being built correctly, which some people have said in other reviews of trays not fitting correctly. This is most likely because it was not built right. If it was built in a factory it would have some more/better quality control.
The second negative is that there is a backpack case that can be purchased separately. It is nearly a must have item. It should have come with it and not be a secondary purchase. The bag isn't the highest quality but it's not low quality by any means, but it's a tough sell to throw an additional 40 dollars towards. However it is a MUST have for the case.
The price for the case itself is a tad on the higher side (especially because you have to put it together yourself) but overall I would say it's worth it. It can easily carry 100+ models of varying sizes. Lets see battle foam do that.
