I received the kit today, and everything looked pretty good. I'm a bit concerned that there's no rubber gasket/seal around the battery door, but nobody else's reviews mention the batteries getting wet. Hopefully it's fine, but I may add one for good measure. I powered on the display, but it didn't default to the setup screen like the manual said it should, and showed no readings from the sensor. I manually ran through the display setup and added the sensor, which it found, but it still wouldn't show any readings. I then ran through a factory reset and it started back up with the initial setup steps. Immediately upon finishing this setup, it was showing readings from the sensor assembly, which it automatically connected to. I then went to calibrate the rain gauge. After a few 1 cup calibration runs, I found that it was not completely consistent, but still averaged very close to what it should according to the manual (1.06") and only ranged by about 5% in the tests. No adjustments needed, good stuff. So, onto the concerns about it losing all settings from brief power outages. After setting it up, I left it unplugged for the better part of an hour, and it still retained its settings. There doesn't need to be such a major concern as there seems to be some level of built-in storage capacitance that keeps the settings in place for some time. However, for those like me who can have power outages on the order of many hours and who want to be able to watch the weather figures during storms, there is an option. The display operates off of 5V DC, which is also the standard USB voltage. You can use a power bank and a USB to DC plug cable to run the display. There are a few things to consider, though: 1) The power bank needs to have pass through capabilities (charge and discharge simultaneously) and maintain the output with minimal or no dropouts when the input power is lost and returned. I'm using the top USB port on a RAVpower RP-PB010 and it works well without any dropout whatsoever when pulling the input power (i.e., acts as a true UPS for that port), and would technically run the display for about two days straight with its capacity. 2) A power bank with lithium ion batteries probably shouldn't be used for this type of 'always plugged in' configuration unless it has overload/overtemp protection and a metallic case for good measure (such as the RAVpower unit noted). 3) The display draws about 280 to 300mA of current, and it doesn't vary at all when the display is dimmed or in sleep mode. Almost all power banks disable their outputs if the load current is too low. Most (like the RAVpower) work fine at 280mA, but there's a chance that some might not. There are still options even if they do, but it would mean adding a load resistor if you're handy. 4) You'd need a USB type A (standard fullsize USB) to 3.5mm x 1.35mm DC cable with center positive *and 90 degree angled plug end*. The angle is important to be able to seat it properly in the back of the display. Overall, it seems like a decent unit. Time will tell once I put it through a brutal Saskatchewan winter, and I'll update my review at some point in the future. EDIT: After a few months in operation, I had issues with the anemometer bearings seizing up. Cleaning and lubricating helped for about a day, but there must have been a bad bearing. Acurite was quick to approve a replacement anemometer/aspiration and expedited it, and I'm back in action. Although some have claimed that their customer service is poor, my experience has actually been quite positive.
