I bought this item before a one month trip. It worked fine before I left, and I used it to check the luggage.
During my trip, it wasn't in use at all and since i was at the same place the entire time, I know there wasn't any special stress or pressure on it.
When I was ready to leave and needed to use the scale to check my luggage, it wouldn't turn on. I didn't have any other options and had to go to the airport and just hope for the best.
I was very upset and disappointed and returned the moment I got back.
The reason I gave it 3 stars is because when It did worked, it worked find, and i'm giving them the benefit of the doubt that my issue was a fluke and that this doesn't repeat in other scales.

I will mention that the build of it has a cheap feeling to it. I don't believe this scale would last for a very long time.
