I am so impressed with this little tape measure! First of all, it was SO easy to set up- simply download the app & create an account, pull the plastic tab on the battery compartment, connect via bluetooth and start measuring. Secondly, I've never had an easier time measuring myself AND it is probably more accurate than any other measurement I've taken! I took all specified measurements- neck, shoulders, chest, waist, hip, thighs, calves, biceps in record time. Pull the tape out as you would any other tape measure, select a body part, wrap it around the body part as indicated, connect the end to the device, press the button to cinch it up, press the check mark and you're done! Measurements automatically saved for future comparison which is great, too! I honestly don't know how they could have made it any easier. What a time saver and boost in accuracy! I'm using it for sewing and to track my weight loss progress.
