Impressed by the device, app, knowledge base, and most of all the reusability
My sister had been trying to conceive and ovulation tests never seemed to show her anything, so she eventually opted for an AVA bracelet. Within a couple of months it was predicting her cycle more accurately than she had ever been able to, and she became pregnant quickly. I was thinking about getting one myself but felt the price was too high for an item that would only be used temporarily and would then be discarded - since it doesn't have any other smart watch fundtions like fitness tracking, phone alerts etc. But I was really pleasantly surprised that they explicitly allow the device to be transferred between people - the bracelet ID is not locked to one user and they even tell you how to reset the data to pass on to someone else. It was easy for me to set up a new account and link the bracelet and start tracking with my own data. So if, like me, you're worried about the waste of buying something that could be redundant within a few months - don't worry - you can lend, give, sell etc if you no longer need it. You can also use it to track your pregnancy (which my sister did right through) - so you may get more use out of it than you think. In the end I only used it for about a week as it turned out by coincidence I'd just conceived before starting with it! But my short experience using it was good - decent tracking, not uncomfortable, easy-to-use phone app, a really impressive online knowledge base that explains how everything works, and a wealth of digital content about health and pregnancy. I learned some new things even though I think I was already pretty clued-up before starting!
