Great for my 4 year old

This watch has been great for my family. I got one for my four year old in the cotton candy color for her birthday. My kid can’t read or write yet, but she loves calling me and sending me little voice messages from school. She figured out how to use it pretty quickly, it’s pretty easy to set up and to navigate. I think the best part is the GPS. I can see where she is when she goes to the park with her siblings, or goes on a field trip. Overall, it’s fun for your child, and peace of mind for you.

Love it

I bought this watch for my 6 year old daughter in the cotton candy color. She loves it and never wants to take it off. She likes showing it off to her friends and cousins. I like to be able to see where she is. So if you want a device that you can track and reach your kids on, then this is the perfect option.

Best Phone Watch

I surprised my daughter with this Fone S4 watch she is on cloud 8. First of all the design and color is so cute. The band is silicone so it’s super comfortable to wear on daily basis. Also just for 10$ a month you have an affordable phone plan. Has fun features included GPS monitor steps selfie pics and regular camera. This is perfect for kids from ages 7 -12.

Easy to use and very nice picture quality.

The watch was made very well strong sturdy band . Clear digital graphics the camera is nice and it was easy to set up and use for my child. I would recommend it to anyone.

Great phone free option

We got the myFirst Fone S4 for my 5 year old and she has been so excited to wear it. The pink and purple colors were absolutely adorable and perfect for kids. The set up was surprisingly easy and the companion app walked me through everything without any frustration. As a parent my favorite features are the real time GPS tracking and the one touch SOS button which provided extra piece of mind whenever she’s away from me. I love that this gives kids the independence of communicating without handing them a full smart phone. She can make and receive voice and video calls with approved contacts send voice messages and I can quickly check her location whenever I need to. The battery life is also very long!Features include GPS location tracking with Wi-Fi positioning voice and video calling voice messaging front facing camera for photos animated emojis heart rate monitor magic button that can be customized water resistance and eSIM connectivity so no physical SIM card is required. The touchscreen is responsive and the watch is lightweight which makes it a comfortable fit on her small wrist. She loves showing it off and I love knowing I could reach her if needed. One thing to keep in mind is that the watch does require an active subscription after the included first month of service so that is something to factor into the overall cost. If you’re looking for a way to stay connected with your child without giving them a cell phone I think this is a fantastic option. It combines communication safety and kid friendly features in one cute smart watch that my daughter genuinely enjoys wearing.
