I bought this to make sure that my bags do not go over the 50lb limit. here are my issues with this digital scale:

- it took too long to beep. I counted more than 10 seconds and I was not getting a beep yet. It doesn't say in the instruction as to how long i have to carry the bag to get the beep sound.
- it gave me an error code every now and then
- the strap was not locking, it kept on loosening up. I thought the strap was not placed correctly  but i tried two different ways and in both cases it was not locking in place.

Thanks Amazon for the easy return instructions.
