The errors occurred just after the warranty period, so I am unlucky.
The numbers on the display gradually started to disappear and can only be seen at a certain angle. When inserting the battery into the charger, wait a few seconds until the basic charging program is activated and then it is possible to change it. If you are charging several batteries at the same time and you are aggressive after consuming alcohol, I recommend not drinking before charging.
Charges AA and AAA
Charging 2.1A via USB 2.0
Numbers on the display gradually stop being visible, poor quality
Battery life absolutely does not work
Charging at higher mA than 200 is incredibly faulty and sometimes evaluates the battery as charged after 5 minutes of charging
the program setting makes me incredibly mad

The charger has all the necessary functions needed to extend the life of NiMH batteries (with the exception of battery temperature monitoring). In addition, it includes a slot for charging via USB connector. In a given price category. excellent choice.

Quality charger. The advantage is the automatically controlled operation and the possibility to choose the charging/discharging current. A big plus is the mains adapter on the cable. The chargers together suffer from the same problem - small cell spacing, so they easily transfer the heat generated to each other. The max battery temperature I measured with a multimeter was 47°C (the charger shuts down at 55 or more). A more modern and backlit display would definitely not hurt and would not be so limited by text or symbols. The buttons should also be better processed, but at least they are not rubber, because with such a number of manufacturers have a problem and are very difficult to squeeze and paradoxically need more force. These are plastic and respond well.
Design
separate mode for each slot
adapter on the cable
charging and discharging modes
current selection
automatic shutdown when overheating
overload and reverse pole protection
indicates faulty batteries
plastic buttons with good response
slots should be wider so that batteries do not transfer heat unnecessarily
classic display

I bought it because I found a box of old rechargeable batteries that hadn't been used for a long time and I wanted to see if they would still be usable.
The Refresh function really works for this, you just have to convince the charger at the beginning to give the batteries a chance. She tried charging some for about 1 minute and then said she couldn't do it anymore, but after repeating it a few times she finally changed her mind. Some over-discharged ones it didn't detect at all, and I had to briefly connect them to another charged one to get it to catch on.
And when the batteries finally catch up, expect the Refresh feature to run for a week or two to have a real effect.
Ability to set mode and parameters for each slot separately
Refresh mode really works, it just takes a long time
Display is not backlit, which would be useful
Cannot charge batteries that are too low

Average charger, with good features, but sometimes it has problems, so it ends up in the pocket of an ordinary Chinese charger from Temu (which I do not recommend)
Charges well
Measures capacity
Refresh, test mode, or even just unload-charge mode
After a year and a half the display has gone, every other segment is visible, which I don't understand (what can go wrong with that? )
They can't handle undercharged batteries, yet it's a simple task, just give them some short pulse and then they'll catch on. I haven't found a feature that allows you to force charge even a low battery.
