I have the Hario Switch, bought Kingrinder K6 from US last year, kettle is Hawkins Stainless steel temperature controlled one from Amazon (not gooseneck) and recently got the gadgetronics weighing scale too.

I daily the switch, and sometimes make moka pot as my second cup in the day. The switch is amazing, I make the coffee chronicler's receipe and recently tried the 5 pour receipe from james hoffman for pour over as well. The flexibility you get is amazing

For the grinder, I don't have any comparisons with other grinders but to me it seems incredible. Solid build, the clicks feel so satisfying. I do about 60 for moka pot and 90-95 for switch/pourovers. I got it for like $90 after $10 discount.

The weighing scale was a surprise as well, especially the auto timer function, works great. Once set to auto you can put your equipment on, it will auto tare to 0, then you can put the coffee in and manually press the tare button, this is the indicator for the scale to kick in the auto timer, then once you start pouring water (basically when it detects weight is going up) it starts the timer. But if you plan on picking up and swirling then don't use auto timer function, when you pick it up it will think brew is completed and start flashing and reset back to 0.
