Control solution did not work

I'm sure this would have been an ok product if the control solution provided worked. I followed all the instructions given on how to do a control test when setting up the meter. I tried it five times, and each of the control results fell outside of the control target range. Either the solution doesn't work, or I have a faulty product. It would be nice to have something that works, because I can't get a good reading until a good control test is done.
