We have had the watch for 2 days and so far it has been very valuable. I must admit, I did not know you had to subscribe to a £9.99 monthly fee this was not clear on the ad. Having said that, safety of loved ones is priceless, so I have paid it without question. It is very accurate and has proven to be worth it. It does say when reading more about it that you should ‘subscribe’ prior to ordering. We received the watch we ordered for £99, then found we had to subscribe to make it work, which was not as intended. That said after the short time we have had it I have been impressed and would recommend - if you are happy to fork out a monthly fee on top.
