taa0007 's Japan Review

It is the cheapest flight protector available, and if you have never used it before, I recommend you give it a try.

Hard to dislodge! But the flight shape fixation is neither good nor bad.

Flight protector protects the center of the flight.
When installed, the flight opens at exactly 90 degrees.
It is relatively easy to remove because there is a recess to catch the fingernail.
