New here and this seems a good place to start/join-in.
I have 3, all Papago, all recording in 1080, (inexpensive, but they suit my needs):
GoSafe 260 (with the optional GPS module in my personal vehicle, a Honda CRV),
GoSafe 520 (switched between vehicles), and
GoSafe 200 (also switched between vehicles).
I'm more retired than not, but still do part-time work driving fleet cars for delivery to/pickup from individuals, e.g. salespeople who have been given a company car by their employer. I may drive upwards of 6 vehicles a day, or 1 vehicle for multiple days if the delivery is far away. I use 1 of the 2 cams to record while driving the company vehicle. My needs are such that I need something that can very easily and very quickly be switched from one vehicle to another.
I have multiple models because each suits a different need, e.g. some vehicles I drive have rear-view mirrors that contain other electronics, e.g. compass, GPS, OnStar, headlight sensors, etc. All those electronics housed inside a rear-view mirror often make it too thick to mount the cam to the rear-view mirror, and some (commercial vehicles/vans) don't even have rear-view mirrors to mount them to. In those cases I use the GoSafe 520 with a suction mount. Lately, I've taken to using only the GoSafe 520 with the suction mount rather than carry 2 cameras, but that still puts me at risk of getting a ticket in some states, because the suction mount is not completely obscured by the rear-view mirror and could count as an "obstruction" to my vision if an officer wanted to be very picky about the issue. Bear in mind that along with the cam being mounted, I also use a driving GPS unit, (I own 3 Garmin devices but only carry 1 with me), and have an LG G3 smartphone with various direction/driving/public transportation apps to supplement those. If I ever get lost, forget where I've been, or can't find my way, it will surely signal the slow, oncoming loss of my mental faculties, (or that my car is out of gas, or all my available batteries/power sources are spent).
I keep the GoSafe 260 powered through the 12V plug in my personal vehicle, (which shuts-off if the key is off), while the others I connect to an 11200 mAh power bank in a neoprene cover with a belt-loop, and use a typical large "binder clip" to attach it to the passenger-side visor, connecting the cam to the power bank with a short USB cable. I have 2 power banks of the same model and capacity , and with them, I can leave the cam running if I have to stop for gas or other break, yet not leave the engine running or worry about draining the car battery. I don't always leave the cam running when I have to stop; sometimes I simply disconnect it from the power bank, but I've driven and recorded for more than 6 hrs and have never gotten below 40% capacity. I've never run the power banks down to zero, nor have I driven so long that they've even had to be switched-out. Of course, I do have to remember to re-charge the power banks, but even that isn't necessary every day. Each power bank also has 2 USB output power plugs: 1 at 1 amp and 1 at 2.1 amp, and a micro USB input for recharging. (An added benefit of the power banks is that they're supposed to be enough to charge my smartphone 3 times, though I also carry a fused 12V splitter, USB power plug, and charging cable for my phone, so I can charge either the phone or the "other" power bank while driving without disconnecting the cam from the power bank in use at the time. However, the Garmin device is always plugged-in to the 12V power outlet of the car, which is what makes the splitter important. Each bank also has an LCD screen that shows remaining capacity, as well as a small, built-in LED flashlight if I need it.
I've updated each cam with the latest software, which, I think, provides use of a 64GB micro SD card, though I use 32GB because that's what I purchased with each cam, which was the max usable size at the time. I record in 5 min. intervals, and with the touch of a button, I can save/protect the most recent clip from erasure/overwriting.
The biggest complaint I have of the Papago models is that the menu and button combination for each is different, hence remembering which button does what on which model is sometimes confusing. Otherwise, each was easy to set-up and is easy to use, as I rarely have a need to change settings.
