Having had no luck with any pole hose for seemingly a decade I thought I would try Gardiners new Ultra-flex. Well, I have to say, this is the best winter pole hose I have ever used! I can also confirm that, although their website states it's not recommended for use with a Univalve (due to it's 'flex') it does indeed work fine with a Univalve- Well- at least with a 25ft pole and cold water! Yes, the pull is slightly longer to activate the valve but not excessively. In fact, the extra flex has an unintended benefit in that it prevents the Univalve accidentally activating with every tiny tug/snag of the hose! It still curls etc but as soon as you pull it, it just straightens back out! Far better than the all season stuff.
If you're fed up of twisted, tangled, knotted pole hose give it a go. Once it's lost it's memory after a few days it's brilliant!!😎👍
