I currently have five and only use one but do keep a spare in my handbag in case I ever want to test while I'm out.
I started off with an Accu Chek Nano as it was very, very cheap, and I liked the idea of the Fastclix pricker, having read good reviews about it. But I really wanted something where I could upload from the meter to my PC, and the Nano had some weird infrared connection system, so was really just a stop-gap while I did more research. I liked it, but found the buttons weren't easy to use for some reason. I got a second one (at a slightly higher price though) to have a spare Fastclix - this was very much cheaper than buying the pricker on it's own!!
Then I bought a Bayer Contour XT, which was closer to what I wanted, and gave me a bigger range of results. I like this but it gives slightly higher readings than my neat little Nano, and it's bigger and (surprise, surprise) looks a bit more
like a meter!!!
Recently I discovered the new Bayer Contour Next which gives more trends and results (over 90 days) and decided that's the one I really needed!! I tried both Bayer and Diabetes.co.uk for freebies, but gave up waiting in the end and bought one. Then lo and behold - a week later a free one arrived in the post!! It reads very close to the XT, and uses the same strips, but it's slightly smaller, better looking(!), and has lots more features, which being gadget minded I really like.
One Nano lives in my handbag as it's tiny, and my husband has the spare one with the XT pricker; he wanted to have a go at testing, as at one point he was suspected of having diabetes.
And no - I don't have any ancient technology leeches lurking around, but my dogs occasionally bring home the odd ticks, which also give me the creeps!
