Is this a good ukulele?

I just answered this for someone else but it applies to your question as well. Usually an ukulele for under $50 is more of an "art object" or tourist ploy" than an instrument that is meant to be played. The give-away usually is if you can't see the natural wood grain because it has been painted over (to hide the flaws). In general the smaller ukuleles are cheaper but they are also the "plinkiest" sounding and may be uncomfortable to hold and play (fingers get too cramped trying to hold more than a one-finger chord. If you really want to learn to love to play the ukulele look at a concert sized like the Lanikai or Kala ukulele. They will run closer to $100 but will be more of what you will keep and treasure as that "first ukulele".
