Yes I have experience using one and I watched my friend use his drying rack for multiple harvests with excellent results.
Good for high humidity and limited space. It dries your buds out faster than any other method as long as you have good airflow.
It might get a flat spot on one side but after it's in a jar or baggies it looks just fine and buds usually get smushed anyways and all his cured buds were round and definitely not flat or pancakes. Somehow or another, away from the luxury of trimming it off the "vine" as a grower, all nugget gets tossed, stuffed, or shoved in a baggie in a pocket and sat on before smoking it.
Nobody will know how it was dried but you.
