Worth the money to me.
PERFECTION. TOTALLY SATISFIED. I AM ABLE TO USE THE FUNNEL ON BOTH OF MY VEHICLES ..... a 2012 ES350 and a 2021 RX350L.
I bought this to use in my Toyota 4Runner and also bought an adaptor so I could use it on my wife's Grand Cherokee and my daughters Jeep. Both adaptors fit the oil fills on all 3 vehicles perfectly and make for an easy clean way to put the oil in while doing an oil change.
This funnel is a smart idea. Screw it into the opening and it does not move (unlike traditional funnels that often have to be held with one hand). Excellent design that makes oil changing easier.
Even though it's really not a big deal to hold a funnel, the threaded one ensures you will have no spills.
