I am looking to purchase a snow foam lance for my karcher. My plan was to buy it from chemical guys as they were doing a good deal with the lance and snow foam product. They are always out of stock when I go on their website and I am very inpatient. I have done a bit of searching and come across this on ebay: KARCHER K SERIES BAYONET FITTING SNOW FOAM DETAILING LANCE HEAVY DUTY 1 LITRE | eBay Seems like a good deal, however I am uncertain if it is any good. Any feedback on ebay snow foam lances or advice on where to get a decent one would be appreciated!
