Hey @hjk96, thanks for hunting this great product! I was looking already for quite some time for a tiny GPS tracker with a long battery duration.

Pros:

• Very small in size; almost like a penny
• Can easily be hidden everywhere
• Long battery duration of up to 3 months
• Can connect to Android and iOS
• It's waterproof

Cons:

• 129$ is not that cheap
• Looks like it is also subscription based (website says "1 Year Free Service")
