Bought two of these for my kids, with the prize and clearly visible plastic frame I didn't have much hope for these but to give them some joy and introduction to music. Both of these have actually performed and endured really well in the hands of small children!
These ain't anywhere near professional, or even intermediate, quality, but for what the prize tag is on these you'll get better experience than you'd honestly could expect! If you've thought about giving harmonica a shot, but don't want to invest that much in just giving it a go, I'd definitely recommend going for these as these'll give you good idea what's it like
