I'm amazed with the build quality, packing, and operation. Video is fantastic. The S-4 spots and follows the subject until out of range and it is very clear and crisp. S4 instructions are very good and the app joins the HB380 without issue. All that said I am very pleased with the units. I bought a second unit to add and replaced five Ring units.
Issue: Living Wisconsin we are subject to some extreme weather conditions. I didn't know that the solar panels and batteries won't work below 32 degrees. I now have two units that have depleting charge and no replacement batteries. I have ordered a replacement battery through amazon and am still waiting for it.
I think to cold weather issue should be disclosed in the details. Other than the battery issue I love the cameras. Also the batteries are expensive. You should offer a discount to purchasers.
