Wow only just read this thread, being a UK based climber and frequent one of the Uk forums there has not been so much anamosity towards the TM harness.
I've been climbing on mine daily for over a year now and its in good condition, yes the buckles look very tatty the anodising is coming off the other ali hardwear, webbing is showing signs of galazing and bunching of fibres, basically the harness is looking heavily used but nothing to be concerned with certainly no broken fibres.
Before purchasing mine I worked with 2 climbers who had the harness since it first came availible, I tried theirs and instantly loved it over my other 2 harnesses (Treemagic and Butterfly 2, only both of their harnesses after a little over 6 months of use showed excessive wear on the leg loops, after contacting the place of purchase they handed their harnesses back t be sent of for repair free of charge. They came back with new webbing on the leg loops, waist attachment and with new bridges plus new ali connecting hardwear that the webbing runs through.
On seeing this first rate service by the manafacturer i did not hesitate in buying myself a treemotion. I've had mine over a year now with no problems and so have the other 2 climbers, the only thing that needs replacing is the bridge.
I'm in no doubt that this harness will not be a durable i never did from the ofset, i don't feel decieved is obvious from its construction. I didn't buy this harnees to last me several years, its all about the motion and comfort.
