October 2024 update:Still going strong! I have NOT been gentle with this scale, and it still works just like the day I got it!Original review:I bought the 120g max version after using the $30 "Gemini 20mg" scales for years. I didn't really read the directions, it does more than I use it for.It seems to measure down to a milligram even if you don't have anything on the scale, I thought I read someone say that is prohibited but i haven't run into issues.You press the on button, it takes a few seconds to boot and stabilize. Instructions say to give it 30 minutes to preheat but if you're like me just measuring out various non-critical supplements giving it only 10 seconds to warm up seems like plenty. (Exception: if you will use it continuously for like a whole 30 minutes without warm-up then your reading might drift but I haven't confirmed).It's very sensitive. Sometimes when I step on the floor in the same room it'll make the reading bounce, so you want a sturdy work area to reduce fluctuations. ... I researched other scales on Amazon before picking this one. So far I'm super happy. I bought extra calibration weights. 1 was a precision 10mg weight and the other ones were a cheapo non-accurate set. ... The scale does come with a precision weight for calibration purposes.As I said before, this scale is accurate. I can weigh out 1mg. Even 0.5mg with confidence, where as this was impossible on my $30 scales without weighing out 20 or 40mg and then splitting what I had into 10 or 20 parts (which in itself wasn't accurate).Item comes double-boxed. This scale is almost 1 foot tall. It is an item you will want to dedicate desk space for, not at all something you throw into an old bin and take out when you need it - it's too big and expensive for that type of handling.Only con is the front label peeled a little bit in the corner as I was unpackaging the box which upset me because other than this cosmetic imperfect this scale is well built.

EXTREMELY well packed and protected for Shipment. No joke. Comes with a very well protected (in its own screw down plastic case) 200 Gram calibrating weight. Best use is to have a dedicated space for the scale; set it up; and plug it in; and let it heat up - and just leave it ON all the time - on a surge protected & battery backup circuit. For accurate results - the scale must be level and 'heated up' and temp acclimated to the surroundings. Glass doors all around. Hook is for weighing something less than 220G - that cannot fit into the window box above. Breezes and such would reduce accuracy while doing this. A stand to put the scale on and use the Hook - is NOT included. I would build my own. Accuracy: 0-50g [+/- 0.5mg] / 50-200g [+/- 1mg] / 200-220g [+/- 1.5mg] The scale does state on the side MINIMUM weight is 10mg. But we were weighing way less than that - no problem. I didn't see what the 'hook' was used for - contacted the seller (Crispaire) and Chris responded soon after with images, explanation, etc. Overall I am happy with the purchase. If you were doing Nuclear Science explosive type weight ratios of extremely small substances - you might wish to spend a bunch more on a scale. But this scale is accurate - it is Class 1 [Precision Lab Work] defined & rated. And you can read about the various scale accuracy Classes online. For example 'Adam Equipment - the Right Balance' has some good info. And much more expensive scales.
