Do you mean a TEE2 blood monitor? I haven't heard of a TEE2+...
It's a good device, but if you don't apply enough blood to the test strips, you will just waste those.
I started with a TEE2 device myself, but have switched since to a
Contour Next One device.
You can get one (full kit, including lancing device and case) for free from:

It's quite a significant step up in term of device quality, more accurate than the TEE2, easier to use, can connect to a smartphone, and test strips allow for a "second chance" to apply more blood if required (so very few wasted strips).
Test strips are slightly more expensive to buy, but can be bough from eBay at around £11/£12 for 50...
