It does the job just fine, for its price it is honest. 2 months maybe 3 now I have it, it charges faster compared to one I got from the store which was for the...

For the money, it is a very good choice. The only flaw I noticed is that it reaches 4.15 instead of 4.2V for the 18650.

Excellent, definitely buy it if you have rechargeable batteries!
I charge the two batteries twice a day for my electronic device, it charges quickly. It stops when they are full. It has an LED indicator. It doesn't charge if you put the battery in the wrong way and it warns you by flashing the LED indicator.

The most quality solution at a price below 10 euros. It has all the necessary safety functions, it is fast, while the disadvantage of powering it via USB instead of a regular socket is irrelevant for those who already have a charging adapter of ~2A from a mobile or tablet.

Perfect for its price.
With a charging indicator, but also reverse polarity.
However, its best feature is the rejuvenation of fully discharged batteries.
I used it to repair discharged batteries of a portable drill and now its battery is like new

For the past two months, this specific product has been flawlessly performing its intended function. It simply charges batteries. The moving parts are smooth and durable, just like the overall material from which the charger is made. The cable has been replaced with a longer one as it did not suit my spatial needs. It is too early to comment on its long-term durability. If there is anything negative, I will come back and update.
