I just purchased two similar units from AMAZON PRIME for less than $20... They were also DROK units... BAYILE is another brand to use... My surprise was the small size of the meter but they work great. Mine were the 100AMP size...
I love using the DONUT sampling of the Dc CURRENT. There is no HOT HIGH CURRENT WIRES running back to the meter panels... I will be running my DC Current meters in the POSITIVE side of the DC circuits here in my setup much like this original one did back in 2009...
I called these donut samplers but they are actually the HALL EFFECT DC Current Transformer sensors where you pass the cable through the sensor with no physical DC connection required..
