RE: Child Locators / Alarms
We have the Mommy I'm Here bear locator. We have liked it, but the battery life is short. The battery actually died in Epcot on the first day of our Disney Vacation. I wasn't able to get the battery cover off to replace them until we got home. So, when we needed it most, it wasn't usable for us.
Otherwise it's a great product and works well. I definitely have piece of mind when we use it. Also, my DC loves to wear it and I've actually seen her showing it off to her friends at the playground. Just keep extra batteries on hand along with a tiny screwdriver.
Hope this helps.
