I use the SD Code Free meter, and have done for a few years. As far as I’m concerned it’s pretty accurate, and most importantly as I was paying for it myself, inexpensive.
My GP’s nurse (not a DSN) insisted I started using this Jazz my meter and then gave it to me free of charge.
First reading I got from the machine was 32.5, which freaked me out, if that was true I should have been on my way to hospital. The nurse shrugged her shoulders and said ‘that’s high’, come back in 2 weeks ????
I went home and rechecked myself with my Code Free, it was high and nothing like the Jazz reading so I called the Customer Advice line. They were very good, we went through a whole bunch of tests (using up my test strips - which they sent out a replacement batch).
It seems that the Jazz will pick up any minute form of contamination and give false readings, so your hands must by scrupulously clean before using it. Not ideal if you haven’t got those facilities immediately to hand, and more importantly, if you have used hand gel at any time close to your test.
