Whilst going to Halfords to buy a new Magic Tree, I spotted amongst the PW extension hoses one that looked out of place.
I looked to me as if it had Karcher connectors, but had no tags on it.
I asked one of the shop assistants if it was priced correctly and he said he could check.
He assumed it was the Halfords own brand and sold it to me for £14.99, bargain!
The Karcher extension hoses usually go for about £30.
Got home tried it out and yup, it's a Karcher extension alright.
Halfords staff can be dim at most times, but it's up to you to use it to your advantage
