Best deckbox I have compared to the cost
This is a great case. Not the best case in the world, but for what it does, it's amazing. I have two commander decks with multiple tokens, sleeved, and there's plenty of space. The magnetic closure has one side or another, kind of, so it doesn't sit straight down. The top also has a bit of rounding so it's not going to protect your cards if there is, say, a flood in your card room or a hurricane in your LGS. But you're not here for that, you're looking for something on the cheap side. The best part about this is that you can pull ONE of your decks out easily, leaving the other one in, with the inner containers. If I was really serious on saving space, I could definitely put tokens and dice on one side and my commander deck in the other, without having to take the cards out of the liner. Just pull the liner out with the deck inside. The worst part about this is the lid is kinda seriously trying to go back to shape, so you won't be leaving it wide open. Very small con though.

Nice and Solid.
This deck box has all the space that you could want. For me, each holds two sleeved decks, extra cards, plus extra sleeves for each deck. Solid and well constructed so I think these deck boxes are going to last me a long time. The magnetic flap holding the box closed is perfect and makes opening/closing the box a cinch. As for style, the glossy pseudo-carbon black look is eye-catching, and the logo is kinda cool too as it goes well with my style of play. I would definitely buy again.

Budget contender, you get what you paid for.
A very budget product. It's priced slightly below most other deck boxes at the time of this review and has the selling claim of holding two. It does indeed hold two commander decks sleeved. That is to say it holds a little over 200 sleeved cards in both compartments. It is magnetically held shut but the magnet is not that strong. The build is plastic but still good enough at the price range. You can remove the two boxes inside the case that hold the decks, but it is a little bit of a hassle at times. The magnetic latch is not lined up properly to the other magnet which is actually pretty annoying. It causes the case to close slightly off kilter and causes the side of the box to open up more than it already should.

Worth it
Monster makes an excellent card holder. Tough, reliable, and exactly as advertised. These are by far the best cases I have bought, well worth their value. It will easily fit a. Commander deck, fully sleeved + sideboard/token cards. Great buy.

Good for cost
Each smaller chamber holds well over 100 sleeved cards, as well as many tokens. For the price, having potentially 3 deck boxes (the smaller ones come out of the big one, but they won’t have tops) is a great deal. The magnet holds, and keeps cards safe and secure. I doubt the magnet would hold against a drop or fall though, but no one is trying to drop their stuff. Overall great storage, but would not protect against any real trauma.

Monster Products Are My Go To!!
Great deck storage, I keep commander decks in this style of deck boxes and for the price it's not bad I'm pleasant with Monster's products. The two trays can hold 100 sleeved MTG cards with sideboard and tokes or 60 MTG cards with sleeves as well, sideboard and tokes. The magnetic flap those a great job holding two decks. Would highly recommend and will continue buying from Monster.

Great buy!
Durability is the only thing this is lacking and the magnetic seal is a little weak but has treated me great for over a year. I love how you can take out the deck boxes individually and there’s room for a whole sleeves commander deck and additional tokens etc.

Best MTG Commander Box I've found!
I have been searching for something like this for so long! This box, unlike anything else I've tried, actually fits 100 sleeved cards comfortably, with reasonable room for a sideboard too. I've had mine for months and had no problems, even when it gets tossed around in my bag! I only wish they had more colors!
