Let me start by saying the company was great to deal with but the product itself is very flimsy. The battery cover won't stay on as it has no way to click in, I can say this is the case with them all as i bought 3 of them in the same order. What I did weigh seemed to be accurate when i got the battery centered and the unit was easy to use. One of the 3 units malfunctioned out of the box but the company was great about it and refunded my money right away.
