I was hesitant to purchase this product at FIRST but I'm so glad I did .My analysis of this product showed that it's perfect for fitness tracking, and the replacement colourful activity clips come in handy when I want to switch up my style. The wearable technology is durable and long-lasting, making it a great investment. The only downside is that it can be slightly bulky on the wrist. Overall, I highly recommend this product for anyone looking for reliable electronics for fitness tracking..
