Also, you actually can modify the EVSE charge efficiency percentage through the app which can dial in the charge % accuracy even closer.
For a Leaf S owner like me, the most valuable thing I find about the Juicebox is that I get the remote app charging features of the higher end SV/SL trims even on my Leaf S. That's worth a lot. Very happy with mine!

After the juice box shuts off the charge at what it thinks is 85 percent if I check the actual charge it will be within about 5 percent. Works ok. You have to set the starting percentage every time....which takes no time.
It's not surprising that it's so-so. All Juicebox's software can do is make an educated guess as to how many kWh should be dispensed to reach a certain dash % SoC. There's nothing in the J1772 protocol for the vehicle to tell the EVSE the attached vehicle's state of charge.
Unless you can make corrections/teach it, will be further and further off as the battery degrades.
