I had heard of it before. And it looks like a nice device.
I wind up changing my own oil about once a year.
And how long i keep my cars varies a lot.
4 years, 7 years, 2 years, 13 years, 3 years...
So I can say mayby.. I just am too lazy to buy one and install it. Since it would be installed at an oil change, and would not actually be put to use for a whole year... [dunno] Though if I bought one and had it around.. Yees if it was on the car it would be easier to do the oil change. The current situation with the oil coming out horizontally is a bit messy. though I have changing it down pat now and usally do not spill a drop.
The one place a person should really get this toy is if they do oil analysis. Then it is golden. You can open the spigot and collect a small sample for analysis really easy. Big plus IMO. [like]
And I agree it is for owners who do thier own changes.
Oil change places are likely to mess it up. And would YOU trust them? They most likely will lose the clip or replace it wrong, they may take the whole device off and replace it with a common self tapping drain plug and not even tell you, they may leave it 'open' and you drive your car out of the oil change place with a steady stream of oil pouring out until you car dies.
