We purchased two of the fourfit mini 2 for our sons for Xmas. Delivery took a while but it did state when we ordered that it was a minimum of 10 working days: arrived in good time for Xmas. We had a few issues getting to connect the watches to apps on the phones, instructions & box stated different apps which neither of them worked.. Found another app mentioned on their website. Emailed fourfit and they came back with some instructions and when we followed them we managed to get them connected without an issue. We were starting to worry after reading other people's reviews but the watches work great and our sons love them. Would be 5 stars if fourfit improved on their communication / instructions for setting up the watches.
