Yes, its cheaper(under $10 on rock auto), I was also hoping a regular socket would fit over it for installation(unlike fumoto). But it didnt so i ended up spending $35+ on a set of crow foot wrenches.
Im not super concerned as the valve faces the rear of the car and requires it to be pushed toward the front of the car and twisted to open, A force/motion that unlikely to occur when hitting road debris or what have you. Also it has 4.4/5 stars on Amazon so that gives me some confidence. I did find the sprinkler effect photo you mentioned on an advancedautoparts.com review.
The hose feature is not applicable to me/us as you still need to be using a pan to catch what comes out of the filter. Unless maybe some sort of filter without anti drainback valve is in use and doesnt retain oil in the filter.

here I test how much oil is retained in the oil pan with the valve installed and the car on the ground. Although the car was probably slightly angled front down as the garage floor should slope toward the drain in the ground and away from the walls. I estimated that it retained 225ml of oil. To fill the pan and filter full i add approximately 3.25 to 3.4L. That means that I am retaining approximately 7% of the oil when changing it without using ramps/jacks and with the valve. Im ok with that.
