I have a few items by RisePro and I am always impressed with the quality of their products. This digital scale arrived and I instantly liked the quality and the stainless steel base with 2 heavy duty plastic trays so smaller items can easily be weighed. It was very easy to set up since it only takes 2 AAA batteries that were included, and you hit the power button, the blue LED display lights up and you can start weighing items. The scale measures in grams, ounces, dram, hundred or pennyweight (cwt), grains, troy ounce, kilograms, tons, pounds (6.6) and carat. Great for jewelry, gold flakes, or even food. It shows auto calibration but gives you instruction on how to calibrate it yourself for the first time. In testing it, I found it to be very accurate when weighing for carat. Good purchase.
I received this product free in exchange for my honest unbiased opinion and I am in no way obligated to leave a certain rating. I rely on reviews when making my own purchase decisions and only provide honest reviews after using or testing a product.https://www.amazon.com/Jewelry-RISEPRO-Digital-Stainless-I2000/dp/B01JGMLTO8/ref=cm_aya_orig_subj
