My wife bought me one of these a few months ago, and overall it is a fantastic pizza oven!! The quality of the pizzas is unbelievable, and incredibly tasty. 

However there are a couple of things I would say; firstly, the door issue is definitely something that could be improved! Once the pizza oven has got really hot, it is definitely significantly more difficult to get the door to fit back closed again. 
Secondly, if you are getting a wood pellet one, I would definitely suggest buying some kiln dried logs for it (you can buy these in sizes specifically for smaller pizza ovens), as trying to keep the fire going consistently if you want to do 3 or 4 pizzas is near impossible on just pellets alone as they just burn through so quick. It’s a shame that the tray for the pellets isn’t bigger, as that would definitely make it a lot easier to keep it going more consistently.
