I got this as a gift before and am still looking for refills or supplies for it.
For something that seems to be based on interchangeable tips, its not that refill friendly.
The good:
The ink is excellent and the tips flow fine.
Switching between tips is easy and fast, they can even be used without the main holder when needed for minimal things.
The case is compact and durable.

The bad:
My problem with it is that after applying a decent amount of pressure when using, one of the finer tips broke and now its practically useless.
They also dry up pretty quickly when uncapped.
It is WAY WAY overpriced. This shouldn't cost more than 15$ if you can't even replace the ink/fills.

I would not really recommend it.
