Review on 2-in-1 Baby Piano Xylophone for Toddlers by Toysery - Musical Instruments Toy with 8 Multicolored Key Scales, Crisp & Clear Tones, Mallets - Ideal for Toddler Learning Toys Ages 2-4 by David Hansen

If it was really in harmony it would be a great toy and I would give it 4 stars. Each note is out of tune by almost half a step. In the end it's mostly fine because they're all out of tune in the same direction except for the root note which is half a step and totally out of scale so it just ruins teaching kids musical tones with that. The keys also get stuck in the down position quite often. When you play it with hammers it works great except the root note is completely out of tune. Could be a good product if they would quality control the tones. . It looks like someone slept in the CNC metal factory and took too long to cut the metal stem of the base note.
