High Quality and super easy to use!
This product is perfect for what it does I’ve used one for thirty years and this is the easiest solution on the market. The cup is American made and very high quality it won’t crack from chemicals like other products do. My other cup has lasted 30 years and I just lost it so hadda buy another. Highly recommend.

The one and only
This is it here boys. This is the original fuel and oil mixer cup, but if you're looking for this you already know that. I'm sure this isn't your first rodeo with this cup. Likely if you've had this cup you know it has so many more uses than that. Don't lie to yourself, you know you've used it for other things. Not only does this excel and getting your oil and fuel mixture correct. It also is a dang good chicken feed scooper, a handy cup to water the barn cats, also great for measuring out pesticides. I imagine its also been found had a couple of crime scenes that involved cooking things that were not food, you know who you are, you toothless hillbilly. For a cup that can do all this the price is a steal. Don't even think about it buy it now.

Didn’t last forever but still good enough for price
The only reason I’m giving 4 instead of 5 stars is because I had to buy a new one after my 15+ year old version started degrading on the inside, potentially leaving junk in my gasoline. You can see it in one of the photos I attached. Still for a ~$10 product that’s long time to repeatedly withstand brakleen and gas. I’ve never had issues reading the markings but if you do you could easily highlight one with a marker since it’s usually used for the same size gas can. This one doesn’t come with a lid but my old one isn’t breaking down like the cup so I just re-used it. Would buy again!

This is the gold standard.
I've had one of these since I was 18 and it's a must if you have a two stroke motorcycle. These are the gold standard when it comes to measuring oil to gas ratios.
