The font is clear and good to look at, looking especially good on screens with anti-aliasing enabled. The one criticism is that at smaller sizes, the lowercase characters such as g, p, and q look quite stumpy and poorly shaped.
Nimbus Mono L
The typeface is reminiscent of those found on typewriters and is much lighter than other monospace alternatives. It does work excellently at small sizes however.
The font is fairly stylish, which also makes it more detailed that many other monospace typefaces. This also prevents it from being suitable for use at small sizes.
