This Dexi was awesome. It worked well right out the gate, lasted through 3 (count them, 3) re-starts. It went to the beach. Near then end she got a cold and sore throat and I said, you know what, I'm gonna give her Tylenol. And Dexi kept on working. The numbers started to get a little wonkier at the end and the tape was getting disgusting, so we gave in and yanked it. I hoped the next one in the box would work as well, but alas, it is not the case.
