Bit of an old thread but there's loads of people with problems with this pole so here's what happened with mine.
I'm a DIY plasterer and having discovered the Speedskim (900mm plastic blade) and finding how it has hugely improved my efforts, I bought one of the Ox Speedskim poles before facing my nemesis, the ceilings .
First time I used it the smaller twist joint at the end came loose. I tightened it best I could but it was still loose so the Speedskim was uncontrollable around the edges of the ceiling. With the plaster going off I rummaged around in the loft for an old pole with the same thread and managed to use that. Not impressed at all with this OxTools product. The pole was cast out into the corner of the shed and I moved on to other things.
Just before the one year guarantee was up I contacted FFX about it. They have farmed out their returns and warranty stuff to some third party so rather than dealing with a nice human from FFX I had to type a load of stuff out on the Claimlane website, upload a video of the fault (which is hard to do on your own) and an image of the whole pole, plus original receipt etc. When I undid the top clamp to show how it wouldn't tighten up tightly (for the video) it then wouldn't tighten at all, it just spun round! If I was a pro I'd just have binned it for the time all this has taken me...
Was told by Claimlane that I had to contact OxTools as they would repair it. I knew my contract was with the seller and not the manufacturer, ie FFX should repair/replace, but I contacted OxTools anyway. They (correctly) told me that FFX should be managing it and sent me back to them. They also contacted FFX and told them this too. I asked OxTools if they had improved the design since I bought mine (2022) and they said no.
FFX/Claimlane arranged for it to be picked up and now I'm waiting to see what happens next...
