KitchenTour Coffee Scale with Timer 3kg/0.1g High Precision Pour Over Drip Espresso Scale with Back-Lit LCD Display (Batteries Included)

i've had it for a couple of weeks now, and i will say, it works well.calibration isn't in the instructions, but, if you hit and hold all 4 buttons when you turn it on, after it says hello, it will enter cal mode. pressing unit advances to the next screen, which is the auto shut off time. if you turn off the power, or use all 4 buttons to reset it, it does not seem to save, so you will have to purchase calibration weights in order to change it. after setting the auto shutoff, it then lists the 3000 g, which is the max weight. it seems you can change it, but i haven't tried. the next shows random numbers, seemingly the raw value of the scale sensor, then it goes through asking for a 500g calibration weight, and after that, a 2000g calibration weight. the 1000g weight doesn't seem to be necessary.after calibration, the scale seems to do pretty well with the calibration weights. weighing in the center and in the corners seem to be repeatable, although it may be a little off at the very edges or corners.the mat that goes on top of the scale has a hangover on the left side, which helps keep it in place, but it can slide up and down.using the scale to measure liquid, it seems to refresh quick enough to easily allow you to gauge when to stop, although, it may depend on how quickly you pour.one thing to note, the precision mentioned in the description. this scale is accurate to 0.1g from 0-500g, 0.5g from 501-1000g, and 1g from 1001-3000g. this isn't over the weight range of the scale exactly, but rather over the displayed weight. meaning, if you decided to weigh pour over or something, in something heavy (or a collection of things), if you tare out the weight (zero it out to measure the difference), it will still display the first 500g up to 0.1g accuracy. that makes the 3000g limit of the scale much more useful.lastly, this is a rebranded scale...many make the same scale under a different brand. i can't remember which combination of buttons it was, but if you held 2 buttons at the same time, it would bring up a muted speaker (no sound) icon, even though this scale doesn't have sound to begin with.i'm very happy with this scale. the price was good, and realizing that the 0.1g accuracy works up to 500g after taring is great. i used it to measure the water and ice in my 64 oz yeti, to figure out how much water i was actually drinking (got very close to the limit of 3000g).

Removable AAA batteries is such a great convenience feature, it means I can put my own rechargeable batteries inside! I'd had this for a few months and have not had to charge it yet, so that's neat!However, the scale is not waterproof, NOT AT ALL!!!!!! The scale is not even water resistant. I barely spilled some milk on this, and it stopped working all together. Thankfully, after drying it off, the scale still works.

I’ve used this identical scale for four years, though with a different brand name on it, still identical, made in China with a friendly “Hello” on the splash screen when you turn it on. After approximately 1,000 uses in four years, it suddenly died one day, lost its mind and became obviously useless. When that happened there was no doubt in my mind that I wanted to replace it with exactly the same scale because I liked the old one so much. The controls are logically laid out, the display is bright, it automatically turns itself off after a few minutes if you forget about it. I’ve tested it with standard weights and it’s precisely accurate. It’s correctly sized for its task (a coffee scale), it’s slim, light, has a removable, washable rubber mat that covers the weighing platform, and is altogether a winner in design and utility, and there’s no reason to change anything about it. When this one fails, I’ll be happy enough to buy another. It costs twenty bucks . . .

Honestly, if you're looking or an inexpensive, accurate scale for your morning coffee or to weigh food, this is great. Is it the most sturdy build out there? No, but those scales are 4-5x more expensive and this is tough enough to live in most non-professional environment.The buttons have great sensitivity and the display is large enough and bright enough to work in pretty much any kitchen. There are no "beeps", which is ideal since I'm the first one up in the morning.The timer has easy start and stop. There is no timer reset short of turning the whole thing off and on again, but what do you expect for $20? If you do want to restart, it's about a 5-10 second process.This scale is accurate, but is not exactly precise. It *does* drift. In static weighing, it will drift around the initial scale about 0.2g. For pretty much everything outside of molecular gastronomy, that's fine. In dynamic measuring, such as when you're pouring hot water over grounds during a pour-over, the scale goes all over the place. The worst I've seen is 2g off in a 500g pour, so honestly not bad, but it's just annoying.Again, I do really like the scale and I thing it's a great value. Is it perfect? No. But at the price, it's plenty good enough.

Why did you pick this product vs others?:I picked this scale because of its size and features. It is small and sleek, and fits well on my counter. It is accurate, precise, and easy to use.Accuracy:Very sensitive and accurate.
