Checking the forums for feedback and this thread pops up,
OP, if you still in the market for these el-cheapo DSO current clamps.?
Just been down that road myself to use with my relative new DSO I got in the start of the year, and acquired 3 of these cheap current clamps, here over the last ½ year, They cost around 100 bucks in total, delivered.
All cheapos from China
Hantek CC65 /20khz / sub60A /38USD
ETCR007AD /100khz / sub60A /50USD
HoldPeak 605A /?? / sub600A /15USD

ETCR007AD got a +/- wheel on the side where you can align.. the Hantek got a degauss button, the 605A its align feature seems to be, focused on a DMM Holdpeak + other brands' often are promoting alongside 605A... also no variable-switch for different values/sensitivity.. recall its 1mv to 1A. and you need some wattage-potency behind the signal, so not good for low current (600A unit).
here a test with a toaster HoldPeak 605A.

The Hantek CC65 is a lot cleaner, actually first thougth the ETCR007AD was faulty, sadly it looks like its the norm with this unit
