Almost Great
It works exactly how I was hoping it would. Holds the guitar in exactly the right position while sitting normally. Very comfortable.<br /><br />Cons. Sometimes the suction cups don't stay stuck. But this is mostly attributed to temperature and humidity changes. I tend to only remove it after transporting my guitar. Sometimes it take a day or so to adjust and then the suction cups stay put again. Suction cup position is also important.<br />Also, I've had this brace for exactly 4 month to the date of this review and the non-slip rubber has started pealing away from the brace in a couple places. Eventually I will need to replace it.
