I bought a Koreel from Gardiners last week and fittings for it from
www.bearingboys.co.uk (in case anyone is interested).
It's a nice sturdy reel and with 100m of microbore and a full hose of water is, i'd estimate, around 2kg heavier than the standard reel that we all start out with (

I connect to the van with Hozelock-type connectors. Those on the inlet and outlet of the Koreel are 1/2" female BSPT - that's a taper thread. According to Redashe, the UK supplier to Gardiners, a regular straight BSP won't fit BSPT. I ended up with a 1/2" male BSPT with 8mm tail (Bearing Boys item: GT21/08K) on the inside of the reel to fit my microbore and on the outside (i.e. the inlet) a 1/2" male BSPT to 3/4" female (RL21/26K) adapter into which I screwed a male BSP Hozelock.
It just take's 100m of microbore. I might lose 15m to be honest as the bearings are very smooth indeed and when you stop pulling the reel continue rotating creating loose hose which is half on half off the reel. Befre I do that I have a question for existing users like Dazmond - does the smoothness reduce a little with time, or is it going to continue to rotate with the initial inertia of a pull even after 6 months?
Cheers
