The case is sturdy and well built. Fits 15 commander decks maximum. I have mine sleeved and stored in the cardboard boxes that come with (all precons), and they fit but not with the life counters (very snug fit). Boulder deck boxes do not fit and have to go in sideways, so can't fit 3 in a row. I have quiver deck boxes for decks I built from scratch and can only fit 2 in a row.
So for commander player, this is really good for storage if you have precons or smaller deck boxes. It's still a decent portable case if you use quiver deck boxes or similar, just know it'll only fit around 10 decks. Compared to the ultimate guard omnihive which fits about the same deck qty, costs slightly less, but is less sturdy and not portable, this still seems like the best option for quality.

The media could not be loaded. I wanted a box to replace my original CAH BBB. (The cardboard dividers on that one is ripping off little by little.) So I took a chance on purchasing this blank BBB. (I preferred The BBMB Logo instead, but wasn't available.)

I am pleased with the box and I have no complaints. It'll hold all the offical CAH + CAH expansion boxes. (Not sure about 3rd party ones that is not from CAH since I do not buy them, if any.)

Even though I'm happy with this and giving it 5 stars, I will mention a few things that I'm nitpicking about the item . This is not a complaint or anything on the people who made this, but just my personal opinions and maybe improve them a little bit in future manufacturings.
1) The lid has a tiny bit of play, even when it's closed and locked. *SEE VIDEO
2) The rubber feet are placed a little inward instead of straight looking. *SEE VIDEO
3) In My Opinion, I kind of wish that the top-inside lid was flushed against the dividers instead of having it spaced out. In my video, I put my cards in faced down (I preferred this way for gameplay purposes.) instead of putting them in, traditionally. So I won't be able to use the box handle because the way I set it the cards, the cards will just scramble inside of it, if I carry it by its handle (suitcase carry).
But again, it's IMO and I also wasn't planning on carrying it like a suitcase, anyways.

If you're reading this, I hope this review kind of helps you on your decision whether or not to purchase this storage box. I know the price is high ( I know for me it is.), but it's worth it, considering it's hard to find a good storage box for cards and all. I don't think it'll disappoint you if you take a chance on it. Have a good day.

If it was just a bit taller to accommodate dividers and a better handle or lid or lock it would get 5 stars

I put dividers in and didn't notice that it was bending the lid a bit. Then it opened and spilled everything. The handle didn't fail, but it feels like it might and other reviewers have shown that it has failed them.

Any of my suggestions would fix that.

Great product, excellent customer service

Great for protecting your cards but definitely doesnt hold quite as many as advertised.
