Seems to be a commercial product, given the small market the price seems reasonable since development cost doesn't go down but the number of units it gets spread across does.
Is it a commercial product? I’m under the impression that what this enables (slow thrust vectored ascent of small rockets) is extremely cool from a hobby perspective as it’s more “accurate” to how large rockets work - but from a raw functionality perspective for small rockets you’re probably better off just using faster motors and fins to stabilize.
Commercial meaning it's being sold for profit and manufactured to be sold for profit. The market is die hard hobbyist but the product is a commercial venture selling to those hobbyists.
edit: Versus an open source project or someone's hobby project just being sold at cost.
