Always Twist & Flex convinced me with
* A very good suction power
* The extremely pleasant to wear, which is mainly due to the smooth surface and the thin bonding
* Very good adhesive strength of surface and wings - because nothing slips more
* Perfume freedom, because this ensures better compatibility
What I find unconvincing is
1) the promise that this binding adjust every move. For adaptability is my opinion at first slip. If that is inappropriate, then can not adapt the best binding.
2) complicates the problem with very good adhesive strength, which leads on the one hand, that the binding can not be mad when she was accidentally stuck wrong, and on the other hand the removal of the bandage from the slip. At least adhesive residues often remain, if not small portions of the wings.
Nevertheless, I forgive like 5 star because convince me quality and value for money.
