I can’t tell you enough how amazing their customer service is and that their products are just as amazing. I can do more tumblers now, no more waiting. I have stacked my Steg 5 cup turner on to my Rex 9 with their stacking kit, so far so good, the turners are always level on their own, with the stacking kit it is still level. I have big expectations and I believe it will not let me down! This has been a lifesaver being able to stack them saving me space!
