Best yet Time Owned: 6 to 12 months.
I more or less collect keys and small keyers and must admit that the MFJ4070D is the best yet. Am used to operating at 25 WPM during contests and this MFJ keeps on going flawlessly. Have tried and own most of the other keyer models over the years with Vibropex being at the top but the MFJ "fits my fingers and brain the best"

Very Good Keyer Time Owned: more than 12 months.
This MFJ product has performed flawlessly for me for over two years. I have only used it with solid state rigs, so I can not speak for how it works with tube type gear. It works well on internal battery or external 12 volt power. I have not had any RFI related problems with it at all, but I am only running 100 watts.

Good job, MFJ!
