The product is defective and I will return it. It trips the circuit breaker on the electrical panel no matter which outlet I plug it into, even after changing the power cable.

I bought a total of 4 of these for the needs of an office located on an island that often experiences minor voltage drops and/or momentary network interruptions. I put one on each computer. They worked well for a year. After a year or so, they started to fail one by one, meaning that with the slightest interruption, they shut down just like all the other devices. Practically, it's as if I don't have them at all. I replaced the battery in one to see if the problem could be fixed, and unfortunately, it worked as it should for about a month and then the same thing happened again. A waste of money.

The review is addressed to the model 600VA 360watt.
Initially, it should be noted that I bought it used from skoop skroutz and according to the seller, it had been used for 3 months.
I have connected it to the Cosmote router, the fiber optic ONT, the landline phone (wireless), and the NVR camera recorder (it works at 3A).
It gave me 1 hour and 10 minutes without any warning that the battery was reaching the end. Obviously, it could last much longer during a power outage, but I simply didn't leave it off power for longer. I am very satisfied with this specific UPS for the requirements I have and for the function I need it for, of course. I would choose it again with my eyes closed.
It saved me in terms of Internet and surveillance cameras!!!

The first one broke within a year, the second one arrived broken from new, unfortunately I had given 5 stars and I changed it

If you are looking for a UPS that will necessarily be placed in a visible spot, it is ideal. It has the LED which functions as an indicator for its operation but also helps aesthetically. Obviously, 5 stars are not just for appearance. It definitely does its job since in two power outages that have occurred since I got it (it is also summer), it kept the network active for over half an hour (I don't know how long it would have lasted because the power came back)

I have had it for 1+ year, and I am completely satisfied. I have one unit with screens and office accessories. It is sensitive to the voltage increase from the power company (and it makes a noise like the UPS is shutting down). But it is good because it warns you about any "faults" from the power company. I see other comments about battery replacement, etc... I do not have such issues.

I can't understand what's happening with the other users. I was late to write a review because I wanted to see how it works over time. So after about 1 year and 2 months, it works perfectly despite the daily interruptions and frequent upload/download chaos in my area. It protects a 55 C1 OLED TV from LG. What can I say, I feel sorry for the other users who have issues. I don't have any problems at all. 10/30/2023, I'm writing again, we're already reaching the 2 years mark and it works perfectly like when I first got it. I will buy a second one for another TV. Today, 11/10/2023, I saw that it needs a new battery. I opened it and replaced it immediately. I spent 15 euros for the new one at a store with batteries and the issue was resolved.

Unfortunately, it smells very strongly of burnt plastic! I have already replaced two (exactly the same) within 10 days for the same issue. The rest are fine, but it is worthless if the smell does not decrease, so it cannot be used indoors.
