3 stars.

Not because the product is crap, but because I didn't do what Waxit Clearly states in the descriptions you should do and call them to discus your particular setup first.

The base end fits the machine perfectly (Karcher K3 around 5 years old ). Zero leaks and only a few wraps of the plumbers tape that comes supplied with the kit.

My problem comes from the fact that I wanted the hose to go with the Karcher OEM gun ( which didn't fit) as I wanted it not just for car cleaning but also to use with the rest of the supplied Karcher Ecosystem accessories I own and I had already purchased an MJJC v3 Foam cannon with the K Series fittings.

Waxit, to their credit offered me a discount on one of their guns that the adaptor kit Purchased would work with and also to refund me the money. Which as it was my mistake I thought was very fair. I went with the third option which was to butcher my lovely new hose and graft on the karcher fitting at reasonable extra expense ( facepalm) but am now very happy with the product.

So don't be an Idiot like me.... Call them and Discuss the fitment with your machine first.
