- Manufacturer claims a booster tip comprised of 6 cutting sides but its sides are so small that they actually form a non-cutting tip. The tip will not negotiate a canal having a smaller diameter without burnishing its way into the canal and resulting in greater torsional stress.
- The finish is excellent and the blades are sharp.
- Testing shows the recommendation of using 2-3 files is overly ambitious as is the recommended use of long strokes for insertion.
