Set gives you a headache

So everything went fine with setting up the set and app but the only problem was the VR set itself. It gave me a super headache and I could not see the cards clearly. I found, that if you just hold the phone up to the card, it worked perfectly fine. There is actually no need to use the VR sets. All you need is the serial number, the cards and your phone!

What happened?!?

I bought this for my dinosaur loving child for Easter (2017) when he was just 2...everything worked great. I put the cards up so they wouldn’t get ruined as I thought this was something he would be able to use and learn from for years to come. Now here we are, July 6,2018, trying to use them again and it’s asking for a serial number. I have no idea where to find that (looking at another review it’s on the instruction card that came with it but it appears I no longer have that card) and now we can’t use the app. This is such a bummer and completely diminishes the appeal of these cards. What a disappointment. I rarely bother writing reviews but this warrants one. Smh. Unacceptable.

Cute! App is a bit frustrating though

I love the idea of this and my son has a blast looking at the dinosaurs! However, I find that about half the time when I start the app up it freezes on the loading page, and i have to force shut down the app and restart. Generally by this time my toddler is pretty impatient haha.
