My biggest criticism of the design of this spool. You don't see it in the photos, but the spool is held together by two pieces of plastic that come together in a crease instead of lying flat; see the photos I took for a better overview). This will cause the bobbin to bounce back and forth on the bobbin holder, causing it to quickly unravel. In addition, the thread is wound very tightly due to the small inner radius and becomes more and more brittle towards the middle. The Gizmodork thread color isn't as light as other threads I've used; they tend to be softer/lighter than expected; "red" has become more orange-red. All in all, if you're looking for a small amount of filament and don't care about things like bold colors or ease of use, this sampler set will do the trick. However, I would recommend other companies like AIO Robotics or Hatchbox if you want better quality.
