The hardware itself or the Control Application? The control application is definitely in need of an update. It's on my list of things to do, but I probably need another couple weeks before I'll have time to get around to it.
If you install the apple TestFlight app and email me your appleID to support at audiofront dot net, I will give you access to the version 2.8.3 Control Application for iOS which should be a huge stability improvement.
