It is a machine charger and I have it for over 5 years, with frequent use on 3 machines and it is ......... P E R F E C T.
Without a second thought. There are cheaper ones, but....you get what you pay for.

It is worth as a charger ONLY for batteries up to 32 Amber, which are for motorcycles and electric scooters or skateboards. For a larger battery like a car, a larger charger will be needed. Overall, it is good and of high quality. It heats up during charging, but don't be afraid of that. It is not a problem. I highly recommend it.

I did not use my scooter close to 2 times. And both times with a new battery that I had taken out of the scooter and charged occasionally, and I saw that everything was fine when I put the battery back in, it only moved forward with the crank. And then if I put it back again, it showed me a problem in the 4th stage that the battery cannot hold a charge.
For short periods of time, it is good, but for longer periods, either no maintenance is done or something more professional is needed, or I should have followed other instructions.

I am completely satisfied with its use. I have used it several times to charge a 12V MF 6.5AH scooter battery, which had been removed from the scooter and left unused at home. Even after 3 months of inactivity, this charger managed to charge the battery properly, and after a day plugged into the house socket, it would go into the scooter and work perfectly. It is worth its money.

Very good charger & maintainer.
Since 2014 I have been using such a device, you plug in the plug and it does its job.

Use for GS GT12B-4 battery, it leaves me satisfied, worth the money, the motorcycle in question is stationary for 3 months a year, I have never had a problem with the battery

Quite good, small and reliable. One of the best battery chargers/maintainers. Connected for three years on two machines...alternatively.

I bought it last year after a little research and some comments on various forums. It is the second winter that I have it attached to the motorcycle and it does its job perfectly. I should emphasize that I leave it continuously connected to the motorcycle for 1-2 months in the garage, and when the weather clears up, the battery is at 100% because after 2 months of inactivity, the engine starts as if I had just covered a 50km distance.

It also includes the accessories that I permanently attached to the motorcycle's battery, and I only connect and disconnect a plug that is permanently located under the seat. Very easy to use.

Now I also use it in the car from time to time when I don't move it. It does an excellent job. It was worth its money
