Edit: Leaving the original review for integrity. Reached out to the company. They responded the following week, as I believe I initially reached out to them on a Friday. I sent them a short video of the issue, as seems to be common practice these days. About a week later, a replacement unit was on my porch. As I unboxed it, I became even more convinced that the first one was a return. There was more going on with the first one than I realized after seeing the difference in the second one. The replacement was well packaged, looks great and includes all of the documentation. Overall, I would say this has been an excellent experience. I do believe there was a mixup with the original unit. It happens. I could just as easily have the same experience at Best Buy. The company responded quickly and, in my opinion, appropriately. I'm currently ruining bacon. So far, I recommend this machine. It does appear to be a new model, though, so extra mesh pads and silicon mats for it don't seem to exist. I picked up some third-party and they're way too small. That's the only downside. As long as this one holds up, I'm very happy with the purchase. I'm glad I didn't go with the six rack. I recommend you don't. Once things are dehydrated, you really do lose a LOT of volume. Original Review: This thing came with no paperwork. There was no warranty information, no recipe book, no instructions. All of these things are available on the website, so no big deal I guess. However, when I opened the box, it seemed as though something had been dripped on the top of it. I've not yet attempted to clean it. Additionally, all of the trays were just loose inside the machine. I ran it through the obligatory first cycle and it seems to be working fine. I'll give it a more thorough look tomorrow, but I'm not convinced that this wasn't open-box or a return. I'll be putting it through its paces during the return period. If everything holds up, I'll update the rating. So far, I'm not super thrilled. EDIT 1: More convinced that this thing was a return. There appears to be a barely visible indentation in one of the top corners. That's not the concerning bit, however. The problem is that the racks (which all measure the same size) only fit in the top four slots. Lower than that they start falling out.They only go in one way, since they're wider than they are deep. I measured the interior width at the door, which appears to be accurate. As I'm looking at it from above, it appears that the sides are bowed out slightly. So the racks will not stay in place. Dropping to a one star, since 60% of the internal space is unusable. Will edit again after contacting the company.
