It's just too small. The donut hole for the fan's circulation cuts way down on the usable surface area. And we can't put small ingredients, like corn, on parchment paper because it would block airflow. I don't think it could do fruit leathers. The instructions are not helpful at all.
Even though they're more expensive, I should've gone with my gut and gotten one with a fan on the back wall. However, if you really do want an inexpensive one and don't need a lot of capacity, this is pretty darn good and good value.
Btw, it's not noisy or wobbly if you have the trays stacked properly. Do not flip them upside down to change space between. Instead, rotate them horizontally 180 degrees.
