I used to transport my models in metal toolboxes, sticking some to the "ceiling" and others on the bottom of the boxes. This was cheap, but I wanted something more modular and where I didn't have to worry about models falling off the top if I set them down too hard!
This case is spacious, and uses that space efficiently. As long as you sort your models by approximate height and do a bit of thinking about tray placement, you can cram a shocking number of things in here! The case achieves this at a better price than other similar products from different companies, without adding any disadvantages. Any "magnet trays secured in a box-like frame" style cases like this have the drawback of being more of a drop risk compared to foam tray cases, which could presumably cushion your models from impact, but the benefit you gain for taking that risk is the massive flexibility they offer. You can swap trays around and easily put different models in this thing based on what you need, whereas foam may be cut to a specific model's shape.
This thing is also sturdy, and the handle feels solid, so I'm happy to make that trade. I suppose other companies offer cases like this that can be transported in special backpacks, but I feel more confident carrying models by hand anyway. None of these types of cases are really meant for planes, but they're perfect for the car and the walk up to the game store.
I do wonder how well the velcro fasteners are going to hold up over multiple years of potential use, but they seem like a simple thing to replace if needed. Overall they are working fine and I expect they'll last quite some time since they aren't under any real strain and you shouldn't be unfastening them *that* often.
Just look at the ridiculous number of Tau I crammed in here. I used to need both hands to carry these models, which represent thousands of points more than I would realistically need for a single list anyway! It's nice being able to have your whole collection for a single force in one box so that you can field a variety of lists without needing to swap models in and out.
Finally, this case has a very special advantage that may apply to a select few of you out there: the trays are the *perfect* dimensions to fit 6 Imperial/Chaos Knight Armiger/War Dog models, OR 2 big knights + 1 smaller one. This means that you can fit a 1/10 big/small type list OR a 2/7 big/small type list into a single box that you can carry with *one hand.* This makes transporting knights really easy as long as you have a list that fits into this archetype (you would have some trouble getting more big knights in here, but you *might be able to squeeze exactly three onto one tray). I attached a picture to show how nicely this all fits.
I will write a follow-up review on the page for the XL case page soon to show you how the two case sizes complement one another.
Overall I'm very impressed, I'd definitely recommend these cases!
