First time smoker and the MES 340G has been a lot of fun to use and has produced excellent meals so far!  First, putting it together was easy.  I had no issues what so ever assembling the product, which there really was not much to do.  It took me and my son just about 30 minutes to do and followed the directions step by step.  We broke the smoker in as suggested and tossed some wings in there as well...  figure why not!  (Tasted oh so good!)  Since then, very easy to maintain, clean and cook great meals.  Temp. maintains setting and the app is really nice to have while smoking during cold Ohio winter days.  Highly recommend for first timers like me and perhaps seasoned smoker vets as well.  Looking to buy this exact same one again as I will likely "loan" this one to my son.
Only downside (that will not prevent me from buying again) is 1 probe, no other ports for additional probes.
