Today I gave the TK419 more of a challenge covering the internal routing hole with the plastic plug and the vacant key hole with aluminum. The TK419 still tracked like a champ. Pretty sure I will be returning the Invoxia. The TK419 does almost everything better, for less money, and seems to track more reliably when hidden in challenging locations. I suppose one benefit of the Invoxia is you can easily swap it between bikes without having to buy multiple trackers, assuming you haven't secured it in a challenging location that makes it difficult to remove, and it probably needs to be accessible for charging. Once I secure the TK419 in my frame, hard-wire it directly to the battery with a fuse for safety, and reinstall the battery lock I won't want to go thru the effort to pull it out to use on another bike, perform maintenance like swapping SIM cards, etc.
Looks like the TK419 can be purchased directly from eelink for $50 plus $15 shipping by ordering a "sample". This is cheaper than amazon or aliexpress. I'd still order from Amazon if you want the tracker quickly. I plan to order another one for my other bike, and since I'm not in a hurry I'll roll the dice on the "SF express" shipping (guessing it will take a month). You can also pay with paypal which adds a layer of protection.
TK419 is 4G LTE vehicle GPS tracking device,the best 4G devices for fleet tracking.Support cut off fuel/ignition remotely and check historical routes and other vehicle data.

There are a few things I don't like about the TK419, mostly related to eelink's (Keelin) app. I haven't found a way to change tracking frequency. Not that big a deal as battery is hardwired. Supposedly you can set up an alert when power is cut and the system is running on the small internal battery. I haven't found the alert to work, but the device does continue to track, then shuts down in an hour. I haven't tested the other alerts like fencing, motion, etc. The app is decent, but it has crashed a few times on my phone. When it tracks a new point on the map there's always an annoying pop up and no option to permanently dismiss. I haven't found a way to have it display the map oriented in the direction you are heading. It's always oriented north. You can manually rotate the map but not something I want to do while riding. Of course, most will use a different app for tracking and navigation like strava so again, no big deal. There is also no easy way to see your entire track for the day. It splits things up into segments (after you stop for an extended period), and you have to view each segment separately. It's also a 2 step process to query the tracking points for the day, not sure why it isn't automatic. Seems like it is geared more towards tracking commercial vehicles.
