I have the exact same poles and have done many km's over several months in varied conditions from easy to fairly rugged.
I have had no trouble with my wrist straps (except being a tad hard to lengthen with thick gloves on).
Otherwise agree totally with Brett.
- Strong enough, but only just, plus I am way shorter than Brett.
- Shock absorbing 'twist to lock' system lasts about a day then just does it's own thing
- plastic 'decorations' lasted me a couple of days before coming loose
- twist to tighten extension system isn't the best, but no worse than competitors similar solutions.
- Colour - red isn't my thing
Now what I do like:
- Grips (material and size)
- Interchangeable basket system (although maybe snow baskets could be bigger)
- Carbide tip grip (not specific to these poles)
Overall I actually do like mine, I forgot them on the weekend and really missed them, particularly on long downhills on day 1 with a heavy pack (it was much, much, lighter on the way out). Having said that the ridiculously expensive BD ones (that Penguin has one of) do look significantly better, especially the flick-lock system.
