Great tiny scale!
I love this scale, though I don’t use it in the way it was intended. It’s designed to assist in making optimal coffee drinks. I just needed a scale with accurate fractional ounces readings. I use it for weighing ingredients for baking, or even light postal packages. It seems accurate, and it very easy to use. I keep it in manual mode, but it also has espresso and pour over modes. It can display weights in ounces or grams, and it has a tare function. The buttons are touch sensitive, so you don’t have to press hard. There is a beep when you touch a button, but the sound can be turned off. I’m a little confused on the charging function. I don’t usually like rechargeable devices, because it makes them disposable, and also because it means they are dead when I want to use them. So I was pleased when it seemed to work while plugged into my fast wall charger. The I read the manual which said A) the scale cannot be used while charging, and B) never use a fast charging power supply. Maybe they’re just trying to protect their liability. I’ll try to be more obedient in the future. The manual also says not to place objects weighing more than 2000g on it, to avoid damaging it. I violated that rule as well and it still seems to be functional. Overall, this is a great, feature-packed little scale, and worthy of someone better than I, who will actually use it to its full potential without breaking the rules.

Wonderful addition
Maestri House makes some great devices for the kitchen. Currently this scale is my 4th item in my MH collection. The scale fits perfectly on my espresso machine and provides very accurate measurements. The buttons respond quickly and the read out is fabulous for those weary mornings when my eyes are trying to open up. The other great thing MH does with their gear is the ease of use options. I flip a switch, place the scale, hit the buttons and the scale works to perfection. Wonderful addition, as always, for another device in my MH collection.

Great scale that needs some improvements to be perfect
Color: White, Color: White
Very accurate scale, looks good in white, timer works nicely and I do like the concept of the ratio conversion. Shown in photos with 0 measurement drift over time, even without the silicone mat. To make this the best scale in the price range, I would change: - The auto timer function. Timing currently stops if you pick up the brew to swirl; you must completely restart the process if you do happen to pick it up. I would change that to only stop on user input (pressing a button). - The ratio conversion. Why offer XX.0 precision if you can only change the ratio in whole amounts? I'd suggest offering 0.1 increments, selectable with +/- buttons instead of cycling through. - The silicone mat is not well affixed and slides around. Kind of useless as-is and I just keep it off. I would wrap the whole thing around the measurement platform, similar to how the Greater Goods scale does it, to really keep it secure. It's not perfect, but for the price, it's a 4.5/5 for me. Rounding up to 5 since a 4 is considered "bad" by today's online rating standards.

IMO, a filter coffee lovers best scale option on a budget. Solid grade A choice.
Color: Black
I have two other .1mg "coffee" or food scales that I used regular for pour overs. I saw this has 4x display on real time flow rate, g/mg weight, timer, and grounds to water ratio for a solid price and purchased this after reading some reviews. One of my scales has these features, but the workflow on this scale just clicked a ton better for me. The beep isn't super loud annoying which is a major relief, as I just couldn't keep sound on on my other scale due to that trigger honestly. I tried brew mode immediately and will now only use that when making a pour over. Loved the beep alerting when I finally hit the proper ratio and I like it keeps my final info on screen after the brew for my study. I can actually practice my technique now and not have split attention as much. This is still compact, but fits a larger carafe well whereas my other scale is a better fit for the espresso machine. The display is clear and buttons have a slight tactile sensation from the print, but are still the capacitive touch based style. I tested it with weights and it is my most accurate scale, it hit the .1g accurately every time or at worst would fluctuate back and forth quickly from the true value (more than enough for me to trust it). It updates and tares from power on fairly fast, it reacts fast enough to touch to not make me pause much. My nitpicks are that the front clear matte plastic isn't quite uniform flat viewed at an off angle giving it a cheaper look, but that doesn't affect functionality at all and truth is, it really was very affordable for the feature set I feel. The second nitpick was that the scale's mat does not grip well or fit securely over prompting it to move around easily. For this I had to modify using some rubberized grip tape on the surface of scale underneath the mat itself. Now it doesn't slide from vibration and if any pressure down it doesn't slip. I could have removed it totally, but it is attractive and useful once stabilized. With that modification done, I can fully recommend this scale for filter coffee lovers at any price. Great product, hopefully lasts me a long time.
