Ditto here. I've bought two from DDM. (Get a spare set of pins when you do; I'm not sure how long they last after you know how to use them, but we had one break under first time handling by a student on Saturday.)
A similar tool for #35 is available
here. As it happens, I'll be ordering a couple this evening, so I can't make a recommendation.
Edit:
For the record, the Dark Soul tool requires slightly different usage for standard duty vs heavy duty (e.g. Vex, and I believe also AM) chains. The difference between the two is the "plate thickness", that is, the thickness of both the inner and outer plates that run from pin to pin. For heavy duty chain, when removing a pin, it is necessary to go to the point of increased resistance, then about another 1/4 turn. For regular duty chain, doing this will result in the pin being pushed completely out of the outer plate, making it essentially impossible to use that link again, at least by using the DS tool.
Also, take care not to over-tighten on pushing pins into the chain; stop just before the screw pin reaches the outer plate of the chain. Even when doing this, I have found it necessary at times to use a screwdriver of just the right width and a hammer to push the outer plates away so that they do not bind on the inner plates -- especially when using standard-duty link-and-a-halves.
OBTW, does anyone know where to source a heavy duty #25 link-and-a-half?

The order is placed. I'll try to remember to post some info back here in a few weeks. If not, send me a PM around 1 August to remind me!

No other hex key, in mm or inches, was as close to fitting as the 3/8" - which works perfectly fine for the other bolt. I was probably just unlucky, but that's still bad quality.

On the first tool we ordered (all I've had in hand so far), the pins were driven perfectly by 5/32" allen wrenches. That was already our most-used hand tool*, so I just bought a couple more!
* - I even have one on my non-car key ring - not only for use on robot stuff, but the "crash door hardware" at the school and church both use 5/32" hex keys to place the hardware in and out of "access from outside" mode. I pretty literally never go more than 50' from my house without a 5/32" allen key in my right pocket.
I did notice some online directions for using the Dark Soul tool referencing a millimeter-based tool (4mm, IIRC).
