After being encouraged by a friend and a professional, I was tempted to try it myself. Appearance - construction - quality - high standards of organization that surpass the "amateur" category. A machine that literally does nothing and you can sleep peacefully without the stress of temperature and humidity, which most machines have issues with. You can even add water from outside without disturbing the incubation conditions. The success rate surprised me as it even surpassed the batches I had recently put. Top choice for its price.
