This is the latest 3G version, seen them in Petbarn for $255, their website is selling them for $189. Use a referral link to get another 10% off bring it down to $170.10, the best part of the deal is no annual subscription fee (normally $71.40 per year/ $215 lifetime), so it's a once off cost only. Note that this is not just a Bluetooth tracker (eg: Tile), but it actually can use 3G cellular network (using Voda/Optus).
Fully waterproof, the battery last 3-5 days depending if it is within your Wifi network, how often you track etc. It comes with 2 batteries so you can always swap them daily if needed. The app is pretty nicely designed. My dog goes everywhere with me so I bought it for peace of mind. Even though it's a "pet" tracker you can use it to track anything (car/boat/boyfriend/girlfriend)
Next year they will bring out more modules (Bigger batteries, USB dock for continuous power supply, flashlight etc). It's an Australian company and their (local) support is very good (tested them).
First post, hopefully it's something worth posting! Thanks!
So about the same coverage as Bluetooth ;)
