I’m seeing the Harmonica for Dummies pack for $15.78 before shipping on Amazon. What a deal, Woot.
I can not speak for the non-string instruments but I can say for certain all these string instruments are junk! They may pass for “wall art” in a den but that would be the absolute tops and that is assuming a lot.
The electric drums are pretty much the same. If you just want to learn how to play without being sure you want to spend money on a decent electric or acoustic kit, these will make the decision for you. Just be aware that these are far from a quality electric set.
