I use it all the time and really like it. and I know I know other folks use it as well. It is however only suited for smaller parts (let's say min 4 square inches, max 500 square inches) of solid wood or plywood and it must be well gasketed, no cracks in the wood and forget mdf since it is too porous.
It is not possible to cut larger sheets on a spoilboard. for that you need a high volume blower with 5 or 10hp or more.
