This item was a gift from the seller in exchange for feedback and I'm happy to report that these binoculars are absolutely fantastic! I have a 3 year old and a nearly 5 year old and they both had a blast using them on our recent nature walks at the local state park. The necklace is great in that it can be worn around the neck when not being held and you can adjust the size of the binoculars for different ages. I also used them and figured out how to change their focus. I don't know exactly what age they are for (might be older kids?) but my kids should still like them even though they were made for older kids. I look forward to using them on many other nature hikes over the years!
