I bought my 10 year old daughter a FourFit Mini2 for Christmas - she loved it, especially how it looked as it came with the funky dark pink strap. It was a bit fiddly connecting up the App, as it took me a while to figure out that the lead for linking the bluetooth connection is via the watch, rather than from my phone. But my daughter loved being able to track her activity, especially mapping her heartrate to exercise intensity and also the sleep tracker. The charger can be a bit difficult to access due to the tightness of the strap housing but overall I think this is a great little device, at a hugely competitive price. Recommended. I see some negative comments below on customer service. I had the opposite experience, hugely positive and super-efficient. After 8 months of intensive (daily) use my daughter's device developed a fault. The FourFit Mini comes with a 12 month warranty, so I emailed customer service. The team were fantastic - responsive, engaged and efficient. I sent through a description of the problem, with photos, and they resolved it immediately. Hugely impressive and first-class service. My daughter is now wearing a replacement device and I will certainly plan to buy another one for the next daughter coming through.
