Based on the form factor and specifications, they are competing with D4v2. So it needs to be cheaper; if it is more expensive there needs to be a compelling reason.
It’s different styling for those who want an Emisar D4 with a slightly different look.
I don’t think it needs to be cheaper than a D4v2, but it should be comparable in price. Jetbeam is using stock firmware and optic so their engineering requirement for this light is cheaper. And it’s competing against the excellent D4v2, which is already out and has the added benefits of more emitter options and aux LEDs.
If this light is around $40 or $50 it could be worth it. If it’s $80, that’s way too much.
I would also request that Jetbeam not do their signature “lets squirt a whole tube of red Loctite into the bezel threads”. At least for the Group Buy lights. No threadlock please.
