I've used the Cholestrak.  It came in about the same as a lab test.

The big problem with it is that it doesn't distinguish HDL and LDL.  You
could have a very high HDL portion of your cholesterol, which would be
extremely healthy, but only see a high total number.

Also, the triglycerides are probably the most damaging portion of
cholesterol for people with blood sugar problems of any type (which includes
a lot of low carbers.)  They typically go down with a low carb diet,
but again, you won't know that with the Cholestrak test.
