Lifetune Flex

poor design the link in the necklace breaks always comes off. the main part itself doesn't do well to sweat. Seems to bend & go out of shape. Need to go back to the drawing board on this seriously. looking at other options now sec one Ive lost!!! Big fail

all the coding peeled off within the first year it's not meant to last and customer service wouldn't do anything for me I would say don't buy it

This item isn’t durable. It’s expensive and no warranty after 30 days. You won’t find/feel anything during this time. After 3 months the top layer will start peeling off and it will look cheap and ugly. I strongly suggest not to buy this item.
