An old article, but still useful:

I don’t check that frequently at the minute as diet control is working for me, but just did it today.
Fasting 6.7 (wth?) ate even more sparingly.
2 hr 7.8... hmm should have been lower (remember, ate sod all!) - used different meter... 5.8!!!
So one of my meters has gone belly up and I’m hoping it’s the high one, but I’m on new meds so really up in the air! Only way to check - yup it’s going to have to be a THIRD meter for me!
My message is - don’t rely on one - it - or the strips - can go bonkers
This too is a 2 meter household.
16th February fasting CF (Codefree) 7.4 retest CF 5.1 retest TEE2 5.6 retest TEE2 5.2
18th February fasting CF 6.3 retest CF 5.0 retest TEE2 5.6
20th February post prandial 1hr 30m CF 6.3 retest CF 5.4 retest TEE2 5.6
20th February post prandial 2 hours CF 6.0 retest CF 5.5 retest TEE2 5.2
22nd February post prandial 1 hour CF 7.1 retest CF 5.1
I could go on ... and on ...
Yes, I had washed and dried my hands, Yes, I did use a new drop of blood each time as instructed by the people who market the TEE2 and, yes, I was holding the meter vertically as they recommend.
I too was thinking of investing in a third meter - an Accuchek Performa Nano. I was on the point of buying online when I realised that Roche don't give VAT relief for diabetics on the Nano, though they do on the strips for it, and also on the Mobile. Boots simply referred me to Roche, who have as yet not replied to my email. So I am totally unimpressed by Roche's customer service, especially in view of the high price they charge for their strips. By contrast, the TEE2 people, although their product is cheap (or free), cheerful and inaccurate, at least offer customer service that simply couldn't be bettered.
When things are going well, I can shrug off the annoyance of meter inaccuracy. But when they are not, it is an added torture.
