Not disappointed in the quality of the product. A beautiful imitation of Glidecam HD-2000 but 4 times cheaper. I use a Canon 70D Tamron 17-50mm f2.8 and, and it is more than enough (I only use 2 weight of 6).
I highly recommend if you are on a tight budget.
Although keep in mind that it takes patience and practice to get a convincing result!
