Charged it up and downloaded the app. Hung the GPS unit on the dogs neck. The unit was accurate within four blocks, which does not work for Chicago.

Finally - a great GPS tracker! I've tried several others and was underwhelmed, to say the least. This Yepzon product does just what it says it will do, works right out of the box and no separate SIM is required. I've checked out the top GPS's on the market, and Yepzon is the most affordable (subscription is required after the 1st free month). Really durable, waterproof, long battery life. Really easy to use. I'd recommend this product to anyone needing some peace of mind ... we're using it to track our child. Also going to buy another to keep an eye on our elderly Mom.

I've been a happy owner of Yepzon Freedom for a while so decided to give this more affordable model a try too. Few dog's have recently disappeared from my neighborhood so I placed this one on the collar of mine. Seems to work well and my pooch hasn't even noticed it. Reasonable price for extra security!
