Owner Reviews, Ratings, Comments and Criticism
No other reviewer mentions what calibration weight this scale requires. An information I wish was available when I ordered it. Although I did my homework I still wasn't able to find this info anywhere. This info should have been sent by the manufacturer to Amazon. The only clue you get from Amazon -even though it is not their fault - is in the "frequently bought together" section where a 50g calibration weight is suggested. So I bought the 50g only to discover (once I opened the box and read the instructions) that the manufacturer of the scale specifically requires a 500g calibration weight for this scale. This information is essential, I believe, and should have been made available to Amazon by the manufacturer. More so, I tried to contact the manufacturer and left a message asking them to tell me which calibration weight they recommend before I buy the scale. They never bothered to call me back. For this I give the manufacturer a rusty 1 star. How you treat customers is almost as important as the quality of your product. For the way the scale functions I give it 4 stars- it seems to work very well for the weights that it is designed to measure - (down to .1 g or 100mg). To Amazon, who tried to fix my problem, I give 5 shining stars! but I'm still waiting to see the info changed here, so that no more people buy the wrong calibration weight like I did, despite all my efforts to find out which one was required! So get the 500g calibration weight if you think you will need one for this scale.
