Post Size Selection
The four available sizes are adequate for most clinical situations, but additional diameters would make the system more versatile.
Post Design
The tapered design of the posts matches the anatomical shape of root canals. 
The head of the post is a continuation of the post without a change in shape. 
Some editors would have preferred less taper at the head portion of the post. 
A change in shape for the head of the post would improve retention of the core material.
Ease of Adjusting Post Length
The post can be adjusted to length by cutting it with disks or diamonds. 
Cutting the post to the proper length can be done easily after the post is cemented and the core build-up is completed.
Radiopacity
The posts have low levels of radiopacity and are difficult to see on a radiograph. The lack of radiopacity of the posts is the primary negative feature of the system and makes it difficult to determine the fit of the cemented post to the prepared canal.

Fit of Post to Canal
The fit of the posts to the canals is difficult to determine because of the lack of radiopacity of the posts. In general, when the radiographs are inspected carefully, it appears that the posts adapt well to the canals.

Effectiveness of Light Transmission
After light transmission, posts were well retained in the canal indicating that the cement had set.
