i have a glyder 40 which was a replacement for the grafter 35 i got with my original system that kept breaking .
they gave me the glider for free so customer service wise they were excellent and admitted they had a bad batch of clamps.
However i use the glider 40 for a few jobs with a very light extreme brush on the end , one of these jobs is at an angle over a very large conny on a big house .
It feels like it is going to break every time i use it and the amount it bends and bounces is unreal.
I have never tried the swift so can't comment on that but both ionics poles i have had have been so bad as to be unusable for the grafter to almost unusable for the glyder .
