The model I have is their smallest one, the Skirmish.
In terms of box quality it certainly feels like a shoebox. It's quite cheap feeling corrigated card, and doesn't have the same sense of stength KR card cases do. It also arrived pre-damaged, despite being delivered inside two other boxes. It will holdup during normal use, but don't expect it to survive a quick shower or light drizzle. It looses a few points here.
The foam is a bit better. It is sturdy, firm, and feels quite good. You get two sheets of foam for models, and a thin topper sheet to protect the top layer. It also fits the case well, with no rattling. It's not the most securely put together though: each piece of pluck is only held on by a tiny amount, so whilst easy to pick out, there is a risk of separation of pieces under heavy use.
The case was advertised offering a capacity of around 32 models. With the pluck foam configuration, you only get about 28. The pluck foam, whilst customisable is incredibly inefficient. Without the use of a knife, about 50% of the remaining space in the tray is foam, when you take out single blocks with a 1 block separating gap.
I had to resort to modifying the slots as it was so wasteful, and it now has much more potential. With some minor surgery, I could easily fit 20 standard infantry models per tray, and the second tray can fit my more unusually shaped models. As it is a small case it's not suitable for tanks or monsters, unless you cut up the trays. I managed to fit a lot of daemons, including:
- 20 pink horrors
- 10 blue horrors
- 10 brimstone horrors
- 4 flamers
- 1 exhalted flamer
- 1 herald
So you can fit a decent amount in, if you are willing to do a bit of customisation to the foam sheets.
If you are after a small cheap case, then the Skirmish is an alright option. If it wasn't free by technicality I would go for another brand, but if you do choose Tabletop Tyrant, it's certainly suitable for the job, and with a bit of cutting and slicing can be much more efficient in the use of space, allowing you to fit a decent sized infantry army in.
