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")
