I waited until this one arrived from Japan to be sure it was really the Polaris before posting here. These retail at around $180 to $200 delivered from local suppliers, mine arrived today and it's the real deal. For me it's the ratio and percentage calculations that make it stand out from the other coffee scales available.

Update 9/1 1pm: Back in stock at a slightly lower price. Was $77.74 on 8/1 11am.

Spiel from https://harioaustralia.com.au/products/coffee-scale-polaris follows:

POLARIS is a smart coffee scale capable of calculating the coffee extraction ratio and visualizing the extraction progress.

POLARIS
The percentage display becomes your North Star, guiding you to delicious coffee.

  • Know how much hot water to pour

You can complete the extraction ratio calculation to prepare the recipe right on the scale.
The scale accurately calculates the amount of hot water you should pour, reducing mistakes in making your coffee too strong or too weak.

  • You can see the extraction progress

The percentage display allows you to see how much hot water you should pour at a glance.
Furthermore, this scale no longer requires the amount of hot water (g) to be poured per pour to be calculated, which was previously necessary.
For example, if you are pouring hot water in 5 portions, pour in 20% increments, or in 4 portions, pour in 25% increments, until you reach 100% while watching the percentage display.
Even if the amount of coffee used changes, the percentage display remains unchanged, making it easier to manage recipes.

    This or timemore basic 2?

      I was looking at the basic 2, flow rate I thought of as nice to have, but doubt I'll look at it, ratios and percentage I think I'll keep using.

      • Mike Nolan on 08/01/2025 - 11:50

        Can confirm, Basic 2 is great but flow rate is pretty useless. Refresh rate much improved over some of their older models though

        • Heybargain on 08/01/2025 - 11:54

          Thanks. The timemore is $44.74 on aliexpress, is the hario worth the extra $30?

          • Mike Nolan on 08/01/2025 - 12:46

            @Heybargain: Can’t say for sure as I don’t know a lot about this new Hario model, but the Timemore does everything I need it to do, good build quality, battery lasts ages etc

            • Stebbo on 08/01/2025 - 13:30

              @Mike Nolan: My Timemore from Ali died after 6mths of light usage. Something to do with the battery connection and won't turn on.

              @Mike Nolan: In case it helps someone, I've owned the Timemore for a couple of years and about a year ago I started having issues with the on/off function and switch. Occasionally the device won't turn on and I have to play around with the switch until it eventually works. If you look online other people are complaining about the same issue. I was going to get the Hario because of this problem but unfortunately it's now out of stock.

      • krazynayba on 08/01/2025 - 22:38

        I have the Basic 2 and am going to return it. The capacitive buttons either don't respond to touch at all, or respond to literally nothing and activate by themselves. I can't count the number of times it has disabled and re-enabled the beep sound by itself without me even touching it. Other than the buttons being absolutely terrible, it seems to work mostly fine. I just feel like I'm fighting with it a lot of the time compared to my old $15 amazon scale

        • tracegun on 09/01/2025 - 17:35

          button issues can be caused if your scale is dirty. wipe it down with a damp towel and dry it.

    • tracegun on 09/01/2025 - 17:42

      i have the basic+ after using acaia pearl/lunars and i much prefer the basic+ cause they both have the same issues due to the design.

      im still using the basic+ after 3 years of getting it.

      the low price and the solid i/o switch was why i got it since i had 1 pearl and 1 lunar fail after about 1 year.

      alot of people have issues with the buttons but the buttons don't work if the scale is dirty (dirt or dried liquids). this is due to the touch button design (not great during service tbh). a wet wipe down will fix this.

    I grabbed one of these recently (the mini) and it's great for me. Looks very similar..

    Edit - sorry just noticed this is for some non espresso coffee. No idea if mine works the same

    • waade395 on 08/01/2025 - 12:51

      I was looking at similar but ended up buying this for aesthetics/size. Really happy with it. No fancy percentages though.

  • eraser215 on 08/01/2025 - 13:12

    Coffee experts… how much has using a scale improved the consistency and quality of your pourover coffee? I am pretty happy with the coffee I make (v60), but can be very inconsistent with my pours. Having said that, I don't want to add more junk to my kitchen gadget collection.

    • Quickshot on 08/01/2025 - 13:26
      +1

      Probably one of the last things you should consider upgrading, inconstancy are more likely from other variables like brew temp, grind size and technique

      • ParadroidDX on 08/01/2025 - 15:40
        +2

        Hard disagree… I would say scale almost as important as a decent grinder. It makes it trivial keep coffee and water amounts consistent. For both pourover and espresso.

        • Quickshot on 08/01/2025 - 16:11
          +1

          Miss read the question. I agree a scale is a must for consistency and accuracy. Was mostly answer if upgrading the scale to this would improve his brew.

          I thought scales were nerdy and I could just eyeball it but they’re essential

        • eraser215 on 08/01/2025 - 20:56

          Awesome, thanks for the feedback @ParadroidDX

    • ozlurker on 08/01/2025 - 15:40

      For consistency a scale is absolutely necessary, if you brew by ratio you will get consistency from day to day.
      I don't think a scale is junk, unless you already have one, a scale is essential in a kitchen.
      If you do have a scale and it is accurate to 1g, you should be able to make consistent pour over, although a .1g would be desirable.

    • fractalsonfire on 08/01/2025 - 15:42
      +1

      If you don't have a scale, you should get one. You'll need it to ensure consistency between brews and understanding what variables contribute to flavour.

      If you already have one, upgrading scales is a low priority unless there is a specific feature you really want.

    • owduck on 08/01/2025 - 15:59
      +1

      Are you using scales now? Little need to upgrade them, but if you're not using scales that would be the main reason why your pours are inconsistent. More so than grind or temperature or technique (as long as you're keeping these the same each time).

      Any kitchen scales would be fine, particularly if you can get ones that are accurate to 0.1g. These have some extra features for making it easier to brew coffee, not at all necessary but nice to have. I like the idea of having it tell you exactly how much water to put in based on the amount of ground coffee and the ratio you want to use. (You can also figure this out quickly with a calculator)

    These any good for espresso or too bulky for that? Looking at getting something for my Breville Bambino Plus.

    • fookos on 08/01/2025 - 13:50
      +1

      I haven’t looked at the dimensions of this one but going by the photo I’d go smaller for espresso. That said measure of your drip tray front to back and see if it will mostly sit there okay.

    • fookos on 08/01/2025 - 16:29

      Also be mindful that Hario’s original scale is/was known for being slow to respond to changes in weight - a bit of a lag. For pourover that is okay but for espresso you need a responsive and accurate scale. This new one may be okay but good to get some user feedback if you can.

      • OZB Al on 08/01/2025 - 19:16

        From my testing today it showed no lag at all.

      I recently got this for my barista express, it's tiny so fits well. Had a larger 'hero' scale that hung over the edge of the drip tray and was way too tall so my mug didn't fit..

    The duality of the OzBargainer - making pour overs at home to save money on coffee out but investing in expensive gear to support the hobby. I love it.

    Putting aside capital expenditure and assuming water is free, I am finding my cost per pour over cup is c.$1.50. This compares to the cheapest external pour over in my area of $6 (average is probably $8-$10 to be honest).

    I really wonder how the coffee makers across Mediterranean (read Itally, Turkey, Lebanon, Greece…) survived for centuries just eyeing the amount of water, coffee and timing to make the perfect brew without using jeweler's scales or WDT combs… Either they had some special talents, or they were complete savages not knowing what a good cuppa looks like.

    3) https://www.amazon.com.au/dp/B0DKZMG9S4

    I typically make espresso and latte's from my machine. If any of the scales help dialing in machine when I buy new beans I would opt for that.

    • OZB Al on 09/01/2025 - 10:27

      This Hario is more of a pour over scale than espresso, so the others you linked would probably be better options. I haven't made espresso in many years, so can't help much. I'm guessing you want to have scales on your drip tray, if so start from measuring how much space you've got on the tray.

    Back in stock and at a lower price of $75.62! Quantity is showing 50 when I ordered

  • fookos on 10/01/2025 - 00:55

    I like the Hario Polaris’ approach to pour over ratios and percentage of pour complete but in the limited reviews and unboxing vids available for this new model it just ‘looks’ cheaply made… Maybe its not like that when seen in person.

    It is the first scale requiring replaceable batteries Ive come across in a while though…

    I’m tempted to add this to my coffee scales collection - mostly due to the Amazon JP pricing - but still can’t bring myself to pull the pin.

    • QUAGI on 13/01/2025 - 16:15

      Same! I have an Acaia Lunar that has been going strong for over 5years now and tired of relying on my phone calculator to figure out ratios (I often opt for the 4-6 pourover method). I also want a bigger scale to handle 4-cup pours and the larger vessells I am using regularly.

  • OZB Al on 17/01/2025 - 11:35

    It's gone up to $83.65. Has anyone else received it yet? I'm addicted to the percentages and am afraid I'm going to start sounding like a fanboi.

    • edsnails on 18/01/2025 - 18:17

      Back down to $75.84 today. I pulled the trigger.

    • Jasonissm on 29/01/2025 - 14:42

      Got mine from this deal, not really impressed with it. I don't like the batteries and also mine started getting drift after about 2-3 weeks of daily usage.

      The ratio calculation is cool, but I usually do the same standard dose for my pours anyways so it didn't really matter to me. I liked the auto timer upon pouring but I kept forgetting to tare the gear before the dose was added which is my bad but also a little annoying.
