I've had limited browsing experience since using the product not used for a full event. I will then update the rating. Receive the package to South Africa a week earlier than planned. Everything was fine and easy to assemble by looking at the 3D drawing. Lights up and everything works as it should. The engines behave like good quality engines and respond well. Benefits1. The engines respond well2. Speed dials to increase or decrease focus and zoom speed3. Comes with plastic rings to fix lens and motor.4. Its light weight. Disadvantages1. I wish there were positive locks for the rear shoulder area and the front area. If there isn't enough or too much pressure on the current locks, something can go wrong.2. The plate that attaches to the camera is not securely attached and may come loose if the side latch is released3. The camera height adjustment has 4 locks, which is inconvenient to use, although you won't adjust it often. I feel the zoom and focus buttons are well placed and have excellent motor controls, they should have been better. pressure sensitive. Overall this is a great product for a low price and I would recommend it.
