"Gig with stereo keyboards? You need these."

Feature:
The dual TRS cables are a GREAT idea! I can't come up with any kind of down-side to this.

Quality:
To this point, the construction appears to be substantial. I'll know more about durability as the miles accumulate.

Value:
I've seen some other products similar to this but they are probably aimed at fixed installations and don't appear to be as durable. Most of the comparable single cables of this type that I have seen are more expensive. I'd say it's a winner on two fronts.

Desirability:
There's nothing particularly compelling about these cables, it's just that they're so obviously practical. As in,"YES! Why didn't somebody think of this before?"

Sound:
I don't think sound quality actually applies to this product.

Ease of Use:
These dual TRS cables greatly simplify the process of set-up and tear-down with a multiple stereo key board rig. Only half as many cables to chase.

Support:
No experience to report on.

Overall:
The only reason I would go to another product like this in the future is if someone could make one exactly like it that was COMPLETELY bomb-proof.
