I got the Heupar, plus it was on sale, so only $130. It'll display up to three 360º lines simultaneously (selectable), self leveling ±4º. If you're more than 4º out, it blinks to tell you. Or you can lock the lines (no self leveling) and then tilt them (tripod/stand dependent). It also came with a magnetic base that also mounts to a tripod or you can mount it directly to a 1/4"x20 tripod/bolt. It's got a battery life indicator with 4 bars. It came in a hard case. You can charge it with USB-C, you can remove the battery and charge it by itself via USB-C, and you're supposed to be able to use it while charging/plugged in. I didn't screw around much with trying the different power options.

I used it today. It does what it's supposed to do.
