Made out of good quality materials!
I haven’t had a chance to installed yet but haven’t decided if I’m going to use as I’m worried it might open.

Installed no issues and no leake. Looking forward to doing 2500-3000 mile half oil drains. Can't wait to see if it holds up and less mess

purchased for a buddy know he will enjoy for many years suck as I have.

Installed the valve during the last oil change. Cleaned the pan and mating surfaces and installed easily enough, but as soon as I added oil back into the pan, it began dripping from inside the valve (not the seal to the pan). Worked the valve as best I could without fully opening it and never could get it to seal. Will be throwing in the trash at next oil change and going back to an OEM drain plug.

Easy to install

Co worker has one on this duramax, after getting a nice armpit of oil he talked me into one as well, fit well and doesnt leak, we'll see how well it works when I drain it again, so far very happy

This has made my oil sampling much easier. No more searching for the drain plug in the bucket. Should have done one of these long ago.

Makes changing your oil faster and less messy. Perfect product, wish I had got it sooner

The name pretty much says it all.
My main review is on the customer service at riffraff. If this was not the Best service I’ve experienced it was sure close. This place is awesome
