It’s very easy to assemble. Sturdy and well built.  Where they are lacking is  their directions for use, how much hardwood pellets or, pieces of small hardwood do you use to start and then maintain the heat?  I ordered the gas accessory, we are still going to give the wood a few more tries.   The pizza so far has tasted good.  I’ll update after we use and make pies a few times with gas.
