Things that struck me:
positive:
- No processing error (the dragonfly but I do not trust)
- Modular design (feet removable, adjustable)
- Stable and no bowing
- The aluminum is actually anodized and not painted
neutral (but worth knowing):
- The bearings are made of simple plastic, not metal or Teflon
- The locking screw can be used in four places (where set screws are standard in it, but all interchangeable)
negative:
- The carriage does not sit 100% wobble-free rail. That's too bad, but probably not to have different for the price (but can be a little hobby work modify)
I saw all in all satisfied! Buy recommendation!
