I must say after hearing so many good things about it, I am disgusted. I spent over $1300 on the 900X Plus, 124-E Battery, 124-E battery extender, and hardwire pro installation, so that I could keep the cam running for 52 hours (their words, not mine). I have a Verizon hotspot to remain live, and I shelled out the $12 per month to get the unlimited cloud usage. Oh yea, you must pay for that too, even though the crappy app rarely connects in the first place. This is in a brand-new Jeep Wrangler. My setup has the hardware with a relay to shutoff the juice from the battery, just in case. Didn’t want to go out one day and my battery was dead, because the crappy app didn’t work correctly. The app is crap and the battery app is even more crap.Here is an example of how crappy this system really is: I came home last night at 5 PM, my battery app showed 100% full capacity. I get notified at 3AM that the cam disconnected. I go out, at 7AM, and the battery is dead. Both batteries. I have been dealing with support (who must think we are all idiots) to no avail.We then get into the crappy app. All config settings are stored on a micro card in firmware. Make one setting change and the entire app croaks and crashes. Good luck changing your hotspot settings. The app will crash once you do. Then, you can’t get into your crappy app over the cloud, because the crappy app doesn’t play nice with long SSID passwords. Supposed to be able to take 32 characters. Eh eh, don’t think so. Support says to edit the firmware on the micro card on your computer using the crappy software. The images they send me, well I don’t have those options. They say, well you probably formatted the card. Ehhhhh. Wrong again. I pulled the card right out of the camera.There is so much more wrong with this system, I would bore you with the specifics.The videos on this cam however are very crisp. When I can see them. Unfortunately, I have been wrestling with this setup for over a month now, so seeing them has been minimum. I am sooooo ready to just rip it out and write it off as bad misfortune. Save your money and buy elsewhere. You will rip your hair out with this crap.I called the installer and asked for his assistance, he gave me great advice. First of all, he couldn’t cover the hardware because I didn’t purchase it there, I purchased it here. But he advised in the future: “Don’t ever buy electronics off of Amazon or anywhere else that you cannot install yourself.” Reason I say that is because I had to return the first cam because the Wi-Fi button got pushed in (or fell off). You know the rest of the story…I took the time to write this short review just so others would know that the golden child “Blackvue” series is utterly crap. Waste of money, time, and brain cells. ### ⭐ 1.0 out of 5 stars Do not buy. *by A***. on Reviewed in the United States on August 27, 2023* Got these for our vehicles. 1mo in noticed they weren't holding original charge. 2mo in, they only hold half charge. 3mo in, they hold less than 15% their original charge.
