I do enjoy my tea.. I think it might be my next rabbit hole to go down. I just got back from a business trip to China, and was gifted a few different black and green teas, loose and bagged. Really enjoying them so far.
I really want one of their...uh... Tea tables(?), which has a tap and temperature controlled kettle and drain built in. I'd drink so much tea...
I'm still learning myself, but it's potentially because the machines are already warmed up and the grinder is "dialled in" for the beans on offer. One very important aspect (among other things such as temperature, pressure etc) with espresso is the grind size, which will need adjusting between different bean types and roasts. Everything else being equal, a grind that's too coarse will let the water through too quickly and give you an under-extracted "sour" tasting coffee, whereas too fine and the water moves too slowly and you end up overextracting (and/or choking the machine) and it gets very astringent and bitter tasting; not pleasant at all.
Alternatively, they could be using a pressurised portafilter, which give much more consistent results, but do take away some control and limit the end result. If it's a high end machine though it's probably an unpressured filter basket.
Edit: Also the roast makes a big difference to how difficult it is to pull a good tasting espresso. Many restaurants/ chains use fairly dark roasted beans which are generally a lot more forgiving than lighter roasts. At least that's been my experience.
I have the Bluetooth + 2.4G one with hall effect sensors and paddles (with the 2.4G/Bluetooth switch on the back and included 2.4G receiver in the dock).
I didn't realise the dedicated 2.4G one received Bluetooth later, but the firmware was for the 2.4G receiver, not the controller, which I'd assume to be the same one regardless? That said, it'd only allow you to use "Switch Pro Mode" and "Xinput Mode" when connected via 2.4G to the receiver. Bluetooth mode behaviour will be unchanged... But given the choice I'm not sure why anyone on PC would use Bluetooth instead of the 2.4G anyway, unless they're not using the dock with that particular computer...
All that aside though, my initial comment was to indicate 8bitdo were actually quite helpful when I reached out to them, in contrast to the person I was replying to... To answer OPs actual questions:
Bluetooth mode outputs as a Switch Pro controller by default, so a lot of games on PC won't recognise it unless you use Steam Input or some other translation layer to convert to Xinput. There are numerous applications to do it, but Steam is probably easiest and most accessible. To set the paddles etc You can download the Ultimate Software on your Phone or the PC to set the back paddles and tweak settings.
I'd recommend playing around with some first person shooters using the Gyro. Steam specifically has a Flick Stick-like mode that is a really fun way of using the Gyro in FPS games like DOOM. You angle the stick to the direction you want to face, and then use gyro to aim up/down and make fine corrections. E.g. to snap turn 180degrees, just flick the right analogue stick down. Works brilliantly when you (eventually) get the hang of it, it's so much faster.
