Review on Lumax LX 1704 Silver Galvanized Flexible by Souly Buddy

I bought this funnel because the hydraulic oil hole is hard to reach. Steel Funnel with Flexible Tube for $10! How can you go wrong with that? I had to add a liter of Kubota UDTs after servicing a couple of hydraulic cylinders. Compatible Kubota tractors require UDT hydraulic fluid, so I have some UDT in the shed. I used my new funnel to fill the tractor with UDT and was blown away by the amount of dirt that was in the new sealed bottle. If that hopper didn't have a strainer, that dirt would have gone straight into the hydraulic system. I don't want to think about what it could do. I don't know if these deposits are rare or happen after the oil has sat for a year, but I now plan to use this funnel for every oil fill I make. What I would like to add is some kind of dust proof bag to store this in. hose before you stow the funnel and I don't want dust to build up on it before the next use.
