Very excited to receive our Kalahari 16 Tray Dehydrator but, disappointed when we unpacked it and noticed that the top fan was not installed - lying loose on the bottom of the unit. The local staff was very accommodating and allowed self-repairs without compromising the warranty after I submitted photos - 4 out of 5 for them. A bit concerning over the quality of the product when trying to remove the back panel to install the fan - some screws were just turning around without coming out. Noticed that they were all zinc-plated screws. Not the best when used on stainless as the stainless is not very forgiving. Expected more when considering the price of the unit. Hopefully, we will now enjoy trouble-free use of the unit
