Thanks for the feedback, Leonie! Hopefully I can give you a bit of clarity around the use of the product, but always feel free to reach out to us directly so that we can help!
In terms of turning it on and standby, it's important to note that your device will automatically be set to 'session mode.' This means that as soon as you switch it on, it will immediately start heating up to the temperature set (the three big digits in the middle of the screen). Once the device reaches this temperature (the three small digits at the bottom of the screen, which will only take a few seconds), a four minute timer will start counting down. For the entire four minute session, your herb will be continuously vapourised and you can just inhale at-will for the four minutes! The kit will automatically shut off when the session is complete.
If you wish, you can press the power button and the 'temperature up' button together to switch between session modes: 4 minutes or 6 minutes. Alternatively, pressing both of the small buttons at the same time will activate 'on-demand mode.' You may find this one easier as it doesn't have a timer, just heats up only as you hold the power button.
As for temperature, I wouldn't stress too much. You may find some helpful advice about benefits of different tempurature settings online or from your prescribing nurse. But, at the end of the day, trial and error seems to be the best way to find your personal preference and the best temperature setting to vapourise the herb you have.
