This thing rocks, super controllable, a blast to tie with!
I really like the fit and feel of this bobbin in my hand - and the control it allows me to have with my thread tensions! Well done.
Super smooth. Design makes it super easy to adjust spool tension with just a squeeze.
Love the feel and really enjoy tying with these. One issue I have had though, after 2 weeks of use, is the "barrel" getting gunky. I've only used GSP 200 so far and when I went to change threads for the first time it was too gunky to get the bobbin threader through. After using my bodkin I was able to clear it out and get my bobbin threader through. Not really sure why that would happen so soon.
