No experience with it, but it appears to provide a space for the comm's clip to attach to without you having to slip the clip between the shell and the padding. Since it's using 3M sticky velcro as the attachment material, if you are only using a single comm unit, I'd just use the unit's 3M sticky attachment instead of the clip.
If you are going to be using a variety of comm units, then sure, why not, but you are still going to have to swap out speakers/mic for the different brands... And this "universal comm holder" is just going to make the comm unit stick out farther from the side of the helmet.
