Napoleon Kettle is good, the lid vent is the major drawback, it can be hart to turn and will rust over time. Ash bucket is a bit on the small side.
The other kettle to consider is the Oklahoma Joe Blackjack.
SNS Kettle, I have to ask myself why? It seems like re-inventing for the sake of it, they also do a Kamado, but for me it is still: Why?
I guess it's all about getting a share of the market. Everyone in the BBQ industry knows that the Weber Kettle are the leaders and constantly selling lots of them all over the world, so I guess make them a little different, add some goodies and sell them in the same market. Youtubers like Baby-Back Maniac will do the marketing for them by doing reviews. You Tubers are a Company's best marketing stradegy if you chose the right influencer with a large following. These guys get 100 of thousands of views so it's not to be sneezed at. It's kind of like asking why Pro-Q decided to make a bullet smoker when the Market leader was the WSM, same reason, it's a good concept, as long as they do something different in design to clear themselves of Copyright and Patents, they get a foot into the market if they're any good. The cheap and nasty copiers don't do well at all except from those who have very tiny budgets.
