Not really universal 1

Not adaptable directly on a Kew Alto 7400. If the original connector fits perfectly into the gun, it is not possible to block because the pins are too long. The adapter is of no use for me.
The seller had the nice touch to attach a card asking to give it 5 stars on its product and that if problems arise, he wanted to be contacted in order to find a solution. This is what I made there are now 10 days. I still await his answer probably never come.
My pipe can not wait for a hypothetical reaction, I gave a big blow Dremel to shorten the two lugs. Easy is the aluminum.
After this mod made in my home, the product has served its purpose perfectly and I was able to find a functional pipeline.
The nozzle received is not at all like the picture. She has a small front and 4 rear jet jets. Better? less good? I do not know. The pipe ahead relatively well in the line provided to accompany him, sometimes forcefully, but hey, the result is there.
I give 3 stars because the price / quality ratio is very attractive and it worked pretty well solved my pb blocked drain that products could not reverse. But unfortunately it is not compatible to my cleaner without modification. And certainly not the 5 star dreamed by the seller who appears to unavailable subscribers (I leave him the benefit of the doubt if he has not received my message).
In conclusion: if you do not mind if necessary to amend section to suit your need, it does the job properly. Otherwise, if you do not have the guarantee that it is compatible with your cleaner, I advise you to look elsewhere.
It would still be simpler than the seller gives a list of compatible devices.
