I bought a new balance with a bowl for 500 rubles in order to weigh bulbs and batteries in the laboratory. The scales were found to be accurate and quite comfortable.
Unlike most household scales, the scale Marta MT-1643 display grams with tenths, while they can weigh loads from 0.1 g to 2 kg.
The plastic bowl is simply placed on the scales. Due to the fact that both surfaces are very even, the bowl seems to stick to the surface and does not slide out. The balance can be used without a bowl.
The scales are powered by two AAA batteries. Salt batteries were included, but I put mine in for testing.
The front panel is covered with a foil. In order for the indication to be as clear as possible, you must remember to remove it (I am sure that most buyers use the scales without removing the film).
The scale has two buttons. Green turns on the scales, changes units of measurement and turns off the scales by long pressing. Orange resets the scale to zero and adjusts the backlight mode when pressed for a long time (always off, always on and auto - 10 seconds of operation after placing the weight).
The watch will turn off automatically after 30 minutes. This is very convenient - my WH-B05 home scale turns off after two minutes and I constantly have to turn it on again.
Using exemplary weights, I checked the accuracy of the scales in the range of 5-200 grams.
Both with and without a bowl up to 50 grams, everything is perfect: for any combination of weights, the scales show the exact weight and always 0 tenths.
With a weight of 100 grams, the scales show 100.1-100.2. With a weight of 200 g - 200.4.
I tried to weigh a lead-acid battery using the two scales I have and these. Miniature Chinese Scales showed 1740.3 gr, scales WH-B05 - 1742 g, these - 1741.0.
It seems that the scales are specially calibrated so as to weigh light objects as accurately as possible, and for heavy ones and grammes, errors do not matter.
I made a short video about testing weights with weights.

The only drawback of these scales is that when you try to turn them off, the units of measurement often change due to the fact that pressing the button accidentally turns out not long, but short (for WH-B05 it is made smarter - the shutdown button resets the scales to zero, and the second unit selects button). However, to avoid this problem, the balance can simply never be turned off (it will turn off by itself after 30 minutes).
I bought these scales in Ozone, for some reason they are mistakenly called MT-1637 there (but in fact MT-1637 this is a scale without a bowl with three buttons), but now they have risen in price there, and in Wildberry there are 498 rubles.
