We had a Heys before and needed a second for when hubby and I are both traveling. This is very reliable. You just have to wait until it beeps for an accurate reading. We've never had issues at the airport using this thing - it's very exact. Just know that some times airports can be rigged - we had one time every bag was just under the weight, and the scale said each one was exactly .5 pounds over. They didn't charge us but were a bit amazed that every bag was packed exactly to the max - I told them - it's your scale that's wrong! It's always exactly!
