Always wondered regarding the cork structure of such "el-cheapo" shuttles.

Finally found a sample.

Pressing the head reveals a soft object? Ribcage structure did not feel solid at all.

For the curious . ...

Soft rubber head instead of cork

Sintec 818 (light blue tube)

Joined a group using the Sintec 818 recently.

Feedback from the visitors (another and myself) are that the shuttle tend to slow down after a few hits. Feather does not break easily but tend to be ruffled easily. Usually require atleast 2 shuttles if anyone smashes during the set.

APAC 800

My group tried the APAC 800 shuttle (black tube with silver lettering) recently.

Shuttle weight is above average e.g felt in-between the Protech Worldclass and Fleet Gold. Rib-cage structure and feather durability was decent. 

Cork structure consists of 4-layers!

Unfortunately quite a number of the players (regulars and visitors alike) fedback the APAC 800 was extremely fast eg like the modified cars from The Fast&Furious after NOS has been fed into the engines!!!
