Far, far too many devices for scribbling.
Should I worry that they include a spanner in order to carry out your own silicone refresh? The most I normally do is fill with ink and wash out for the next colour choice.
You shouldn't worry at all - it's a feature of all TWSBI packages that self-service kit is included, and it's honestly not that trick to use. It is also so much less frustrating than having to send a pen back to the factory when a simple problem occurs!
