Before the pump how many meters did you use

Hello all,

For some who have been on the meter for a short time I wanted to ask how you all managed to adjust to  tracking the results. Right now my son has 4 different meters. ONe at home that records and downloads, one in school at the nurses office and one in each family car. Typically there are a lot of numbers to transfer. Of the meters two are different manufactures and are not compatable. How did you all manage that.
