I found them too small for me so I gave them to my granddaughter for her birthday. She loves them. She is 4 and I am 80.
Once I realised how they worked they were fantastic. I couldn't understand why they wouldn't change colour and thought that there was a fault. All we needed to do was to disconnect from the charger and the flashing sequences work fine. Instructions would have been helpful but great product. Grand-daughter will love them, just hope they fit.
Great trainers, very well made and excellent service to boot.
