Bonvoisin Digital Lab Scale 600g x 0.01g Precision Electronic Scale LCD Display Analytical Balance Jewelry Scale Scientific Scale 0.01g Accuracy

Many of us have bought these scales for our labs for HS stem classes. These work well and are inexpensive. They last well even in adolescent hands, calibrate easy, and give adequate measurements which are reasonably accurate. Lightweight but robust enough to be moved and quickly set back up. Make sure scales are level and calibrate with weight

Does the job !

EDIT: After 5 days use, I've determined that the precision is improved when additional weight is placed on the balance. Usually by 1) adding an object of about 60g along with the weigh dish, 2) taring the weigh dish and extra mass, and 3) placing the sample onto the balance slowly and from a short height, I can take 10 measurements, 7-8 of which will be identical. The seller/manufacturer was very polite in response to my review, and I encourage anyone to try this balance for low-resolution gravimetric work (and spend some time with calibration weights to learn its nuances). Seems the scale's 0.01g resolution and is precise to about ±0.005g.You may have the following experience if you are not sufficiently careful with your balance:Spec sheet says accurate to 0.01g, but it has a significant level of inconsistency. Weigh the same item 10 times and you may get 5 values that are the same. I wasn't expecting milligram precision, but at least SOME reproducibility of measurements would be useful. If you purchase this balance, I recommend placing your sample in the tared weigh dish and weigh it ten times and use either the mode or the mean as your measurement.

I chose this scale because of the long auto shutoff time, which is useful when you are mixing glue. One thing though it doesn’t want to work with rechargeable batteries. Seems odd.

Decent quality scale, maybe not medical or lab grade but good for home use. It's good for measuring small amounts of supplements or other small food items and it is pretty sensitive. For the price it is not bad. The scale is easy to use out of the box and is pretty self-explanatory. Has battery and plug in capability and the LCD is very easy to read.

The first one lasted a year, then wouldn't turn on.The second one lasted a month and won't turn on.

Had an issue with a foot, which the seller quickly fixed—props for that.One drop of thick/dense fragrance oil moves the needle 0.02–0.03g. I’m no scientist, but seems precise to me!

I had this scale for 7 months and it will no longer turn on. It worked fine when it was working. Would recommend spending a little more on a higher quality product.
