If they hadn't been putting out unrealistic hype for years people might give them a bit more slack for a seemingly competently engineered product. They presented themselves as having some revolutionary proprietary technology. In reality almost everything here is off the shelf components being assembled by some unnamed third party manufacturer. The only unique part they make themselves is the "photonic chips" which aren't actually that revolutionary, other people had more or less the same idea and decided the benefits didn't outweigh the problems.
