Attention. Do not buy this mirror. There is another brand that costs about half the price.
Now let's move on to the description.
There is a vertical strap on the plate. The fact that the strap does not go horizontally across the head makes it useless. You cannot adjust the angle to see your child. Also, it does not have a base to adjust the mirror. You simply have to loosen the strap and come up with different solutions.
Also, the child in the mirror appears slightly above their head, but in miniature.
Even those with perfect vision struggle to see their child.
I address all the parents out there, thoroughly check each product and do your research before making any purchase. Reviews are not enough.

The child's toy is very small and I don't understand what it does. Okay for the money, I didn't expect anything more.

It's fine! Just the right size. Although it only has one strap for vertical fastening on the seat cushion, it is quite stable.
