It's a bit unfair to rate it because I had ordered a similar one with different specifications. However, the other one was ultimately not available, and I had to go with this one. I got it for a vacuum cleaner, and it charged very slowly. The thing is, I couldn't find anywhere in Greece the charger I wanted (and the one I found on Skroutz, they didn't actually have it). In short, make sure it has exactly the same specifications as the charger you want to replace in both Amper and Volt.
