Used maybe a dozen times max. Was in the bag the rest of the time. Excellent condition. Upgraded to the Ursa Mini Pro 12K and when it's fully rigged out it pushes the weight capacity too much so I've been shoulder rigging, using the Sakk, and using sticks far more.
If you have mirrorless bodies rigged out or even smaller cinema cameras this is perfect for you. Takes a lot of strain off your arms and shoulders and redistributes the weight. Saved my arms a ton the times I did use it.
Retail is $1259 and used for over $1000 + tax at B&H so this is more than fair.
