I put together the upgraded model. I haven’t cooked w/ it yet, but definitely appears a lot better. I also like the fact that the instructions indicate the different amounts to utilize in reaching the desired temperature. Keeping it at a five. Customer service ended up being fantastic.Update: June/18th/2024.At first I was not pleased with the original product. The expertise in customer service not only made it right, I would now also personally recommend their product.Very impressed with their customer service.Having said that, my four is now a five.Thank you!Update: Customer service reached out to me &they are working with me for a resolution.Update: I purchased the $60 oven door that wasn’t included w/ my original purchase. The door arrived today, however it does not attach. The older model oven does not have two top tabs to attach the door. I’ve purchased a lot via Amazon & this is by far the worst experience I’ve had. The representative advised me that I do not know how to cook pizza, lol. I’m guessing all the one star ratings given by multiple folks w/ the same problems also need pizza cooking lessons! The seller did give me a $20 credit for my inconvenience, so the oven door that doesn’t work actually only cost me $40.?The last picture is of an oven that has the tabs on the top to attach the door.The older model does not include a front door closing to keep heat in.The product that is advertised is misleading. The one I purchased was an older model that doesn’t cook correctly. A modification to the older product was made (front door) and applied to the newer model. Older model does not work & now have to buy the door to fix the nonfunctional older model. I’m not the only one with this issue according to the reviews. I was offered $5 towards the purchase of the upgraded modification that costs $60. Very unhappy.The first photo is the one I bought. The second one is the upgraded version with a front door to seal that is advertised. [...]
