40 years and still going strong.
RPN for the win!
Snuck my new watch into the pic (-;

Hi @Andreas.ca - picture of the 12C brings memories as I used one for many years. Built like a tank and totally reliable! It was always great fun if someone asked to borrow your calculator and were then totally mystified why it didn’t work properly - mysteries of RPN to the uninitiated!

The HP was nice, but the rocking keys need too much pressure and the screen/digits far too small.
Here’s the best desktop calculator for everyday use.
Casio jw 200sc. It’s slightly oversized, but not too big. The keys are soft and definite. The adjustable display tilts up to a perfect desktop angle, but the main advantage is the display is great quality. The digits stand out from all angles. As can be seen above, compared to a typical calculator, the display is in a different league.

Ah, that brings back memories of my first calculator: Sinclair Scientific, bought in kit form when it came out almost exactly 50 years ago, costing an amazing £12 or so, against which the cheapest alternative scientific calculator on the market was over £100. Multiply by 9 for cost in today’s money.
Plasticky case and with red 7-segment LED display it drained its twin AAA batteries in just a couple of hours, however RPN notation very logical and didn’t take long to get used to, and it served me well for about 4 years until I got a Sinclair Enterprise programmable.
I still have both, though it must be getting on for 40 years since I last used one. They were great calculators for their day, excellent value fir money - though sometimes I feel nostalgic for the non-electronic calculator I had before them, something like this:

I bought a Sinclair Cambridge in, I guess, 1973. It was amazing. I made a pouch for it to hang from my belt. Very basic calculator, but I was very pleased with it. Long gone now, though.

Stopped looking when I saw the = sign.
Not RPN and doesn’t fit in my front shirt pocket.
After a bit of research I’ve come to the following set:
- Timemore Nano 3
- Hario V60 Zebrang
- Hario Drip-Assist
I’ve added it to my birthday/Christmas list and will purchase anything not received. In addition, as mentioned, I’ll get a cheap and small coffee scale of Amazon.

I can’t honestly say it’s the best because it’s the only one of its type I’ve tried. But it makes life so much easier!!
Self adjusting wire stripper from Amazon Basics.

Does acetic acid react with CO2?
E.g. if you put apple cider vinegar in fizzy carbonated water?
That’s got way too many buttons

No, no reaction with dissolved carbon dioxide gas. However it will react with any dissolved bicarbonate or carbonate in the water, of which there could be a low level in the water, especially mineral waters, but the only practical effect of the reaction would be a slight increase in the carbon dioxide.
Yes, I had no idea what most of them did.
Would have been much better with fewer large buttons.
I can get into enough trouble with a standard one without all those extra buttons.
So why on earth get a scientific/available calculator?! 
Because I was 10 and that was the one that they told us to get the school I went to, or maybe it’s just the one my parents bought me.
To this day I hate using spreadsheets, but am pretty good at data analysis and not bad at specifying what data should be gathered to answer a particular question.
I have uncanny knack at making good guesses numbers.
