If the manufacturers really stick by their marketing material, they should have no problem signing a service agreement with guaranteed production and efficiency targets, and a 100% refund if those targets aren’t met. If they’ll agree to that, giv’er a try. Otherwise, I suggest anyone looking at an ETHOS system do some deeper due diligence into actual user experiences with those systems. (Hint: note how many have been listed for sale just on this site.)
I know of more than manufacturer that has signed agreements like that and had to take machines back at the end of the day.
Of course, they never revised their marketing material because those are not the standard terms and with multiple months worth of orders in the hopper it doesn’t matter to them - they just re-sold the units to another punter.
Equipment manufacturers in this industry have little to no incentive to improve their designs because of the massive demand. If you make something that is even marginally not terrible, you will have lineups of people waiting to throw money at you. If that’s the situation, why would you bother improving or re-engineering your systems?
Yes, that’s short term thinking, but that’s this industry in a nutshell. Fuck next year, I’m worried about today!
Disclaimer: I have no experience with the Capna system, never used one myself. They seem like nice people when I talk to them at conferences and expos. This is entirely my opinion, and I’m not directly affiliated with any other equipment manufacturer (I have however done some consulting work in the past with various parties doing not dissimilar things).
