is the car engine diagnostic code scanner sold by Groupon any good?

[Adam]

The CAN OBD-II is sold for about $14. Is this limited or good enough? Anyone here tried it?

It’ll be very limited.
A lot of plug and play code scanners can also give you the wrong codes sometimes, especially on newer vehicles.
If you’re only planning on using it to work on your car and maybe some friends then yeah, it’ll give you codes that you can look up and help you fix the problem but you won’t be able to pull up specific codes on it, or see live data or anything.
