The problem is that if the issue is technical they can’t fix this next year, because their hardware in the field won’t support field replacing the laser. That is, can a user snap out the old laser (and associated parts) and snap in a new one? If they ship units out that can’t be field serviced, it’ll have to be shipped back forever.
If the problem isn’t engineering but their lawyer, I’d suggest fixing the lawyer. They need to figure out how every other laser company has figured out how to sell replacement tubes to customers.
And if they really can’t support selling replacement parts for people to install, they should work out a business arrangement so that “send all units back to GF for laser replacements” is a viable for customers. For example, get fixed rate shipping pre-negotiated, and ship out replacements immediately, then have people ship the broken units back in the same container for a credit back. Then the down time is just the shipping time from GF to the customer (an businesses can pay rush shipping) and people don’t have to save huge boxes for years. Lots of equipment companies do this, and customers love it.
