I run cuddebacks and have two of their cell cams. I run another 3-4 (one is a floater that I sometimes move to an area out of range) off those two cell cams so effectively have 5-6 cell cameras.
When they're working, I have zero complaints. On occasion, they will struggle to find service and you'll get stuck with a cell TX message that stalls out the cell plan. This happens maybe once a year, if that. I had to have one camera replaced because of this and it's essentially an error that is started by low cell service and then a big queue of images unable to send.
Picture quality is really good! Wish they had video option like tactacam but they don't. Trigger speed is the best thing about Cuddeback. It's phenomenal!
Battery is okay but I run solar panels and/or battery packs on all of my cameras now. Most are over a year without battery changes.
Overall, they're great cameras that happen to have cell capabilities and if you want to run more than one camera and only pay for one plan, it's a great option.
Happy to share more if needed.
