Perfect for a desktop computer, the battery is easily replaceable, with only 4 screws on the bottom. The battery should be replaced every 3-5 years.

The Cosmote router was not functioning properly, so I returned it. It is obviously related to the "waveform" it produces at 220v. It may be suitable for other devices. I only kept it for 4 days, so I don't have a long-term opinion.

I bought this specific UPS about 2 years ago, which became faulty in a relatively short period of time and was replaced by the company with a new one of the same model. I am not satisfied at all with this machine because 9 out of 10 times, it fails to keep my PC running when the power goes out. It's as if I don't have a UPS at all. I still have it because I hope it can at least maintain a stable power voltage and for the money I spent. I do not recommend it to anyone!
