Not Tested under fire of course, but it works fine so far. With the exception of a few untrimmed sharp points and edges, it appears very well made. The buckling seems arcane to me but I suspect a fancier easier system would add cost, and these though not super easy to mate, do seem safe and functional. Overall, a Good value for what I paid (bought 2, but my wife seems reluctant to use hers and go up in our just acquired 55 ft Digger Derrick truck's bucket), as far as I can see. Since it is my first such safety harness, my comfort and ease of use ratings are not really well grounded and are strictly my impressions.
