Let’s try a couple things:

New batteries, as obvious as it seems please try some fresh batteries. Rechargeable AAA batteries are the
go.
Check the metal contact points are free from any rust, corrosion or residue. Use a butter knife or flat head
screw driver to scratch off if you see anything like that. Otherwise it will block the power from the battery.

Still having any problems after trying these steps please send us a short video of the product so that we can assess what the issue is.
