Great
Had a splash guard come off my Honda and these were perfect and so easy to put the splash guard back on. They are very durable and good quality. I recommend these!

Fit as described
Used to install an inner fender liner. Seem a little more fragile than OEM, but suitable for the intended use and much less expensive.
