I impulse bought a Pilot Metropolitan (F) about a month ago and have had the worst experience so far. First it took 3 days of experimenting (squeezing the cartridge, flushing, cleaning, shaking, incessant scribbling) to get it to write at all. Then I noticed the nib was a bit off-center in the feed so I aligned it and it wrote pretty well for a while. This morning I grabbed it to take some notes and it won't start, even after a flush with water and re-seating the cartridge. This isn't my first fountain pen (not even my first Pilot!) but I'm really disappointed because the Metro seems to be such a popular recommendation as a solid, inexpensive starter pen. Did I get a dud?
Where did you buy it, and what kind of ink are you using? Metropolitans are really reliable, so it's be very surprised to see a dud unless it wasn't a real Metropolitan or the ink was India ink or iron gall ink. There are Lamy Safari fakes and other similar pens sold on Amazon. I've had better luck buying at pen shows and from trusted retailers.
I did buy it on Amazon, but it was shipped and sold by them so I trusted that it was legit. The ink cartridge was included with the pen. After fussing with it some more and reading all the responses here I've decided to return it for a refund. Guess this is a lesson to stick with more trusted retailers, I've been lucky to never receive an Amazon fake but I guess there's a first time for everything.
Honestly, I think it is probably a dud. I have yet to see "imitation" Pilot Metros on AliExpress like I see with the Lamy Safari. Duds happen. I wouldn't sweat it as long as you get your refund.
