Yes, it's a good feature of battery-powered small cheap scopes that
they allow ungrounded operation.  As you note, some of them can't
capture I2C, which I didn't think about WRT the cheap scope I linked.
It does 250 KHz, not good enough for `Fast Mode` I2C at 400 KHz, let
alone the 3.4 MHz and 5 MHz versions of I2C.

Amazon shows other low cost scopes with 2 channels and higher bandwidth. Their operation is entirely by menu choices which is initially confusing for me, a user since the big vacuum tube Tektronix era, let alone a newbie to scope use with only a vaguely worded instruction sheet and no other owners to ask for help.
I use Amazon as an aggregator of similar items, for an overview of what's available with user reviews, not necessarily as the seller I buy from.
