Arrived earlier than expected. During my investigation, I was able to reduce my options down to the yeti and echo flow. The echo flow was unavailable at the time due to a lack of resources. The blueti has exceeded my expectations. Very sturdy construction. Everything I wanted and more. I bought it for a number of reasons. Off-grid camping and live sound audio are some of the things I do in my spare time. I need a reliable, high-quality power supply for live sound. Since it's done well in all three tests, I'm considering using it for house backup power in the event of an electrical outage. Because it's tough to view the screen in direct sunlight, I wish it had Bluetooth communication with my phone.
