As rackmounts go, they are fairly straight forward. With this, there could be a few improvements. There is a couple of holes on the front plates for your cable to go from your amp to the back of the AKG wireless. These holes are small! you'll need to remove the head cover on the jack, put the cable through and then put the cover back on. And we all know, with some cables they aren't 're-use' friendly, so you'll need to make a cable really. The screws that come with the rackkit, to connect the side rack to the AKG wireless unit are very short! I mean, extremely short. Now, maybe the problem is with the wireless unit, maybe the screws can not enter too far. But if this isn't the case, then its just poor.
But saying all this, its a rack kit, it works, and is handy. Could be improved though.
