The Good Stuff:
Off set inflation stays clear of 1st Stage
Elastic retractors are great, I use them to tuck my hoses in, keeps it all neat
Retaining clips stop the wing from "hot dogging" round your tank
2 lower pull dumps
Its Zeagle, so it's going to last.

The Not so Good Stuff:
Shoulder strap loops are a pain if using a one piece harness, ok if not swapping between wings.

Would I recommend one? YES!
