I model the "barbed wire".
The security system is well thought out, reliable and easy to use.
The strap is nice and comfortable.
After less than a year of use low intensity (I am not pro musician), the "ring" plastic (used to adjust the length) was broken during a concert. Fortunately, this has not brought down the guitar, just the total elongation of the strap.
I do not do it again this election, I will turn to a stronger strap, strap locks and buy.
