[EX Q]: I got two bottles for my newborn with no issue. On the third bottle, discovered a dropper that wasn’t built into the cap. Not sure if it’s a defective batch or what. (Which means you’d have to wash the dropper every time... not ideal at all.) I submitted for a return/replacement and the fourth bottle I got had the same issue. If this is just a new design, I’ll definitely have to just switch brands. :(
[EX A]: negative

[EX Q]: I bought this for my daughter and we were so excited about it. It worked for maybe 20 minutes tops... I thought that maybe my batteries were bad.. nope. We tried several different batteries and it still doesn’t work. It’s a cute puzzle, I just wish it still sang the song!
[EX A]: negative

[EX Q]: I never received it. How could I give you a review of a product that was never shipped and I have never received? I paid for it, still don;t have it, and the delivery company keeps promising they will deliver it, but never show up. Doesn't say a whole lot for Amazon and the shipping company.
[EX A]:
negative
