5CH Big Size J3 With Brushless Motor

The dog works as expected. The dog itself is rechargeable via the included USB cable, The only downside is that they do not include the wall plug for the USB charging cable. This is fairly common though and wasn't an issue as I had several around the house from old phones. The remote takes two AA batteries. I let the dog charge up overnight and it was ready to use in the morning. The dog worked as expected and all controls were labeled well and easy to get used to. I was able to use the robotic dog on both the medium pile carpet I have in my house and of course on the hardwood floors with no issues. The dog was easy to get to go where I wanted it to after a few minutes of getting the controls down.One thing I didn't realize was that the dog also has some basic learning built in with the "Study" button. This plays songs and other things while the eyes change their led's to go along with it. One example is the Alphabet song in which the dog sings the song and the eyes change to the letters being sung in the song. This was pretty neat and a fun way for a kid to learn.Overwall, the dog works as expected and I have no issues at this point in tim.

Worked great first few weeks after that the remote would not work for it

Awesome little toy. My son loves it. So do my dogs they get a kick out of chasing it around. It moves well on the carpet and wood floor.

got for my son and worked fine on christmas morning but the next morning is only walking in circles

Kid friendly!
