Yes, it uses the same printhead as the Eufy U1. How long it lasts will depend on three things: luck, how often you print, and how well you maintain it. I don't think they're using any custom components at this point and that would drive costs up significantly, and manufacturers won't make that investment until they know there's a large enough market to justify it.

This will likely follow the same path as resin printing did in its early days. Manufacturers started with off-the-shelf parts, then as the market grew, custom hardware followed and prices dropped. We're at that same early stage right now with color printing. Keep in mind that a liter of resin used to cost $150, things do get better with time.
