The quality is decent for the price. And in most cases, it is working very well. I see three areas where this can be improved.
1. The product I received has a defect where the left throttle lever lock can separate (the triangular guide separates from the part where you pull with your fingers) that maybe resulting from the mold/die having too much error. I see the same issue reported in the AB6 comment section so I'm not the only person with this issue. Maybe something to incorporate into the quality control process.
2. The rod that locks the left and right throttle lever is too short, sometimes they separate when only one side is being moved. This is somewhat annoying and may need a redesign.
3. The wheel on the left throttle lever and the knobs have a significant input delay. If you turn them in one direction, you can see the virtual button being pressed repeatedly with a delay. Then if you turn them in the opposite direction, you'll see both virtual buttons being pressed repeatedly, with the newer input fighting the older input. Therefore it's very easy to overshoot and it can take ages to correct. For trimming, it's better to hold the virtual keys instead of repeating a short tap over a period of time. This may be fixed by a software update.
I hope MOZA will improve the product based on the feedback. As the company is new in the flight sim market, I expect to see much better products after a few iterations.
