Im very happy with my bushlite. Its robust, the arms might need a bit of bending to fit smoothly into the sockets,as has been said, but they're pliable, copper or brass, and its not gonna do any long term damage. In fact about 20 seconds work with a pair of needle nose pliers and they now fit perfectly.
You will find that over time that copper and brass will work harden with being bent, this will make it brittle. OK it may take a bit of time..
to demomstrate it take a bit of wire and bend it a number of times
