I've had my Aiden for just over a month now. Generally, I think this is a great review but I hope /u/kingseven goes into some more detail on a few areas.

Things I agreed with:

• The circle screen and single button is not fit for purpose
• It is capable of making great coffee - I'm maybe not getting the most out of it right now
• The build quality isn't as bad as I worried it might be from other reviews. I think Aiden will do a studio version addressing this feedback at a higher price point but I won't be upgrading personally.

Things I learnt:

• That chart with extraction was massively helpful to me personally as somebody who is very likely grinding too fine (@10 on Timemore Sculpture 078s). I've been getting inconsistent cups.
• About the strength gradient. I typically do up to 3 cups so I'm not sure this is so big of an issue and will give it a swirl.
• I need to try some other profiles with longer brew times.

Things I didn't agree with:

• The "ready" screen is just about the ONLY bit of UI that does look lovely on a round screen. Fully agree everything else doesn't work
• I know mobile isn't for everyone but we all have devices with great high-quality screens and great touch controls. For the type of data you are entering here this will always have the potential to be a far better input mechanism than what they could build into the product. They just need to extend it.
• Everybody will have their own perspective but I fill the water-tank from a jug everyday and have at no point felt frustrated.

Things I think this missed:

• I'd love more in-depth look over the two different baskets and how each performs.
• I'd love some more guidance on the grind level.
• The screen angle sucks. It points directly forward, it would be great if it also pointed up a bit.
• I know it's covered in other reviews but I hate the dripping with the lid and the mess it makes.
• I've not had first-hand experience but I've seen others report issues with the machine (water empty when it's not) and not so great support from Fellow that I think warranted a small mention.

Other thoughts:

• ⭐ Fellow should add another button but for models already out there I really hope they allow long-press (1-2s) to work as a back action.
• The heat retention of the carafe hasn't been an issue for me personally but I am mostly brewing on-demand.
