The tool we have been waiting for
This tool makes a stage manager’s and sound operator’s job much easier. It is also a good value. It might be more convenient in some cases to have the Telephone Power supply as part of this product, but there are times when having the controller separate is an advantage. I withheld a star (grudgingly since I love this product) because the labeling and build quality could be better. It does not in anyway effect the operation, nor do I think it will have an effect on the life of the device(s). There are other products available that do some, or all, of what this one does. Most are significantly better, and aside from an extremely expensive device which is no longer available, nothing I have used works better.
