Smart scale with eight sensors for 1,749 CZK. It recharges and doesn't need AA batteries

A personal scale is one of those things where most people don’t understand why it should be smart – until they try tracking their progress over time. ETA Vital Condition 8779 now with code ALZADNY30 comes out to 1,749 CZK instead of 2,499 CZK and measures significantly more than just kilograms.

👍 Get it, if you want to track the development of your values over time and appreciate that the scale recharges instead of constantly searching for batteries.
🤔 Hesitate, if you expect medical precision – bioimpedance measurement in home scales serves for orientation and trend tracking, not for diagnosis.
💰 Price tag: 1,749 CZK for a scale from a Czech brand with a two-year warranty

Eight sensors instead of the usual four

Inexpensive diagnostic scales usually have four sensors placed under the feet – thus measuring only the lower half of the body and calculating the rest. Eight sensors mean more accurate and stable measurement, because the scale works with more points. In addition, accuracy to 100 grams and a capacity of 180 kg, so it will serve the whole household.

The scale measures body fat, muscle mass, and BMI and connects via Bluetooth to the ETA Body Balance app for Android and iOS, where, according to the manufacturer, it evaluates over 56 body characteristics. However, the main benefit is not in a one-time number – it’s that the app stores history, so you see the development over time and don’t have to write anything down.

A practical detail that everyone will appreciate: power is handled by a rechargeable Li-ion battery, not AA batteries. This eliminates the classic scenario where you need the scale and it reports dead batteries that you don’t happen to have at home. The platform is glass, the display is backlit, and an overload indicator is present.

How to read measured values

Realistic expectations are needed here. Home scales measure body composition using the bioimpedance method – a weak current passes through the body, and the device estimates the proportion of fat, muscles, and water from the resistance. The result is influenced by hydration, time of day, and whether you have just eaten or exercised, so take absolute numbers with a grain of salt. It makes sense when you weigh yourself regularly at the same time and track the trend, not individual measurements.

On Alza, the scale currently has a rating of 4.3 out of 5, but only from four customers, so not much can be gleaned about long-term reliability from the reviews. It’s worth noting that ETA is a Czech brand with its own testing lab and service in the Czech Republic – for warranty claims, this means a significantly simpler process than with anonymous scales from marketplaces.

Do you weigh yourself regularly, or do you prefer not to step on the scale?
