This is a Tanita baby scale. It has been used for a long time, so there are signs of use and dirt. That's why it's priced low. I've included photos of it actually measuring. I've checked it several times and confirmed that it's reproducible. There is sometimes an error of plus or minus 5g. However, since it measures in 5g increments, I think that's unavoidable. When actually measuring a baby, they move around, so the measurement error can sometimes be even larger. Photo 12: 5kg of rice only (image before breastfeeding) After turning off the power Photo 13: 5kg of rice + disinfectant wipes (image after breastfeeding) Photo 14: After pressing the breastfeeding amount button (image of breastfeeding amount) The difference is the disinfectant wipes, and Photo 15 is a measurement of only the disinfectant wipes using a kitchen scale for confirmation. I checked it this time and it mostly worked well, but sometimes the breastfeeding amount calculation doesn't work. However, even in that case, the weight itself is displayed correctly, so you can calculate it yourself. The main unit has stains and yellowing in places, as shown in the photos. The sticker on the back is also slightly peeling off. The battery cover feels a little loose and tends to come off easily. The mat is deteriorated and dirty, but you can still use it by putting a towel on it, so please consider the mat as an extra. The box is also damaged because it was used for shipping. I don't have a box of the right size, so I will reinforce it with tape when shipping, but please understand that it is only for shipping purposes. The rice and kitchen scale are not included. This is only the baby scale itself. There are no instructions. I may have overlooked something due to my amateur inspection. Please understand that this is a used item before purchasing. Due to the above condition, it is priced quite low. I am also open to price negotiations. Would this be suitable for those who just need a rough measurement, only use it occasionally, or just want to measure as a reference? Thank you for your consideration.
