Other paintball companies have matched this low-cost, low markup marketing concept (examples being the Proto Rail (based on the Proto Matrix), ICD Promaster, Eclipse Etek Ego (based on the Planet Eclipse Ego), and others). However, these competing products are notably less popular in comparison, likely due to their higher price tags, although still remaining very economic alternatives to their respective "high-performance" counterparts. The popularity of the Ion also allots it a massive amount of upgrades and specialized products, and like the older Impulse literally every part of the marker can be replaced with an aftermarket version.
