Compared to Alesis's other drum kit options, the Crimson II isn’t as popular. While Alesis still manufactures and sells the kit, it’s not as quickly findable as other products. The reason it’s not as popular is that Alesis has a few kits in the $800 to $1300 price range that are very similar to each other. Since the kits are so similar, it’s typically a buyer’s choice to go with the cheapest option, which isn’t the Crimson II. After speaking to multiple drummers, browsing through drumming forums, and constantly reviewing gear myself. I’d say that the most popular kits from Alesis are the Alesis Nitro Mesh, Alesis DM10, and Alesis Strike Pro.
