The glasses were great! The ice molds were a let down. Only one of them held water and the other is essentially useless because it doesn't hold the seal and water seeps out only making 1/2 and ice ball. Pretty disappointed

This does not work properly. I gave it 1 stars only because clock works. It does not track steps correctly. After shopping yesterday it said I went 3 steps. Hello.........I would not recommend anyone purchasing this product if you want to track steps.

I got a used one which must have been returned. No instructions, hardware was opened and looked like a random assortment in a ziploc bag, literally, see my picture. I wasn't able to figure out how to put it together without instructions and with the hardware provided so I'm returning it.
