Most common complaints

In owners' own words

“that's a tough sell”
— @i.d.6209 on YouTube
“The only extreme downside to the ECO is that they BREAK! I've broken 4 of them so far. The plastic is extremely brittle, and if you press down while you write, the nib is pushed into the feed and will crack the feed.”
— @k-ozdragon on YouTube
“Twisbi Eco is extremely overpriced compared to Kakuno”
— @YzorYzor on YouTube
“It's 50 dollars now :(”
— @grottjam on YouTube
“metal does not cost that much. I don't see how the need to replace it with plastic.”
— @smileandlaughs on YouTube
“its not justified . Its over priced .”
— @Nadeemkhalid07 on YouTube
“I have problems with my ECO. One day the cap got stuck and I had to open it with force.”
— @Die_Schreibmaschinisten on YouTube
“My TWSBI ECO <M> skips like hell. Maybe it just has a bad nib? I would pick my Safari any day of the week.”
— the-computer-guy on Reddit
“My biggest purchase disappointment so far; absolutely lacking adequate ink flow when it comes to note-taking writing pace.”
— @7_v610 on YouTube
“I do my journals with a twsbi eco. Personally I find it to be a bit too smooth, I like tips that scratch a bit. It's so smooth that I almost loose control of the movement, and it feels like the tip is waterplaning. It also suddenly skips and hard starts randomly.”
— Yaatun on Reddit
“I like how the TWSBI Eco 1.1mm stub writes, but the barrels on my TWSBIs always develop cracks and leak all over my fingertips.”
— Necessary_Rest_9421 on Reddit
“I too have a TWSBI Eco that won't stop leaking. I've tried pulling the nib/feed out and re-seating. Doesn't work. It was a few months old. I trashed it.”
— Paratrooperwife on Reddit

Setup quirks & things to watch for

Not complaints — practical notes from owners that didn't affect the score.

“My experience with TWSBI Ecos is that they're also wet except maybe the EF that is average.”
— Pop_Clover on Reddit
“I had a TWSBI Eco EF and if anything it wrote very wet”
— bioinfogirl87 on Reddit
“mine writes a very thin line. It definitely feels like an ef so might be a paper/wetness thing? or just inconsistencies with German nibs lol”
— A_Firm_Sandwich on Reddit
“I also have a couple of ecos but they are un-inked and not getting any attention cuz I love the swipe so much. None of my twsbi pens have cracked.”
— anonymous on Fountain Pen Network
“Later I bought a twsbi eco for a stub nib but realised stub nibs are not really my style but it's always nice to explore”
— VAnish_186 on Reddit
“I did have a little bit of trouble with posting initially, because it takes a bit more of a shove than I usually apply to that task”
— anonymous on Fountain Pen Network
“A TWSBI ECO may be a great first pen, but since it’s a piston filler, it wouldn’t provide the opportunity to work with a converter as the ink delivery system”
— PaulFleming75 on Reddit
“I contacted TWSBI once to ask if I could change one of my ECO nibs, and they answered that they are not supposed to have interchangeable nibs, so they do not recommend removing it.”
— RemoveIndependent597 on Reddit
