Nagging VRInsight CDU II Issue, Duplicate Presses sent

Hello All,
I am having a nagging issue with my VRInsight CDU II, which looks like other folks have had it as well. In a review post, the author noted "The only remark I have here is that the CDU II sometimes sends double inputs to the pc upon pushing a button only once. Sometimes annoying, but nothing terrible."

Here's a link to a YouTube video showing it happen. At 2:13 (ish), you will see the user enter "LFMP", but it puts two L's in place. This also happens with the CLR and DEL keys, which you can understand why THAT gets a bit difficult for someone, especially a newbie at working with the PMDG 737 NGX FMS like me.

Also, here is the review I refer to earlier in the post:

Has anyone else seen this, or found a resolution to the issue?

Best Regards,
Brad

On my cdu I press the button on the edge of the key,try not to rush the key presses,this works for me.
