I've got one, and I love it to bits. One of the biggest things for me is that it actually encourages me to test more to keep a better eye on what is going on, and the trend graph it produces is enormously useful. It's so convenient - I've literally just scanned mine using my phone whilst walking down the road - and very, very easy to use. On one occasion, I was having a very bad hypo, and slept through two alarms, which is not like me at all, and my other half had to test me using my Accu-Chek metre, which is a bit of a challenge if, like him, you aren't good with blood!
Of course, I'm very lucky to have a generous relative funding mine, so cost isn't a consideration. However, the prices are slightly lower than quoted on the website as, in the UK at least, if you are buying it as a diabetic, you don't have to pay the VAT.
