Best luggage scale I have found. We have purchased a couple of luggage scales from walmart and they really were not that accurate. Love that it is digital. Trying to hold the bag and read the other scales is not accurate. Another great feature is that it has a measuring tape built right in so you can make sure you do not go over the size limits with the airlines. You can weigh in pounds, ounces, kilograms and JIN (not sure what that one is) . This product runs on 2 AAA batteries (not included). The instructions are super easy to follow. If you travel alot this is definitely a tool for you. Small enough that you can throw in a briefcase or purse.
