Twsbi Eco Cap Falling Off

[Drone]

Hi, The all clear TWSBI Eco is out...

 

Has anyone done a comparison between the new and old models to see if TWSBI did anything to fix the cap posting problem? Or did TWSBI just pretend the problem doesn't exist?

 

From the pictures I've seen the new and old pens seem identical. But it wouldn't take much for TWSBI to change the barrel dimensions slightly to fix the posting problem, a change that would be impossible to see on a Web site photo.

 

Thanks, David

Push the cap all the way down until you find it encounters a "damp" resistance, like gummy-bear-like. The cap never come sout after months and moths of use.it is not meant to be capped, either... And I think it looks odd when capped.

"Not meant to be capped"?? Then why do they have the O-ring to hold the cap firmly in place? It is *designed*to be posted, for those who wish to do so but on some pens the air seal produced by the O-ring causes a build up of air pressure, and the cap comes off. I haven't experienced this on my Ecos, but it appears to be a problem for some!

Yes it is designed to be posted. But when posted, weight of cap makes end heavy. So I find it unbalanced for my hand. So I use mine unposted. Plus it is nicely balanced unposted.

I have a hard time imagining anyone - even with large hands - finding it comfortable to write with posted. This would be a non-issue, except for the ring.

I use my ecos posted. I also post my 580's but I also have very large hands.

 

My gripe with posting the eco is that when you post the cap, the o ring might trap enough air to prevent secure posting. This does not create an air tight seal however. My strategy has always been to push the cap down and hold it if only for a second to allow some of that air pressure to release or even neutralize. At this point the o ring provides enough friction for the cap to stay in place.

 

The design elements are there for posting and understandably this isn't ideal for all, but for me it's the most comfortable way to write.

I find the Eco to be most balanced when posted. As of now, I still haven't had any issues with cap jumping off.

Has anyone considered risking a mod to the pen to fix this? One could grind a small hollow inline to the body under the o-ring to make it less air tight.
