My Leki Microvario Carbon poles, after limited use, are apparently irreparable (a combination of the stuck/collapsing button, and internal cord wear reported commonly on the web; so clearly a design flaw).
Leki are not minded to replace, which is very disappointing given they were a premium product at a premium price.
Thus if you get no support buying top end, I may as well go cheap.
Are the decathlon poles any good; do they last?
What other short pack length & light poles do people recommend?
