There are so many voltage and resistance ranges on the market. Here are some specs I sort out， just for your reference.
Voltage range：1.8V, 2.0V, 2.4V, 2.6V, 2.8V, 3.0V, 3.2V, 3.5V, 3.6V, 3.7V, etc.
Resistance range: 1.4ohm, 1.5ohm, 1.6ohm, 1.7ohm, 1.8ohm, 2.0ohm, 2.4ohm, etc.
And for live resin or rosin, 2.4V seems to be mentioned mostly. And everyone says they have the best disposables for live resin, so you have to test on your own to figure out what devices exactly fit for your concentrates.
If you still need any alternative disposable vendors, pls feel free to contact us, samples are available for your testing.
