Maginon 4K Action Cams are a favorite for risky shots where you don't want to destroy your $400 GoPro.
The same camera is available under several other names, but the Aldi packaging comes with 2 batteries, and a giant pile of extra mountings..
In this year's version they added a remote control wristband (works up to 33 feet away), and a dual battery charging station.
From past experience, many Aldi stores will have this in the front office, not out on the floor; so ask if you don't see it.
