i'm aware of all of that - i just retired last year after nearly 40 years in manufacturing. The problem or question i see is, the Hobart at price points not far south of $10,000 are nearly 5 times the retail of the KWS. Granted the Hobart's price, i'm guessing between 25 & 30% is because of their name recognition and market dominance, and their service network (warranty & parts availability), with the balance of their price (70-75%) being due to cost of production & their profit margin. If their profit margin were too great, you'd see a number of US mfgrs offering similiar meat slicers, but you don't. Which gives me a clue that their profit margin isn't exorbitant - but i assume they're obviously producing a quality product.
The KWS brand, i can't even find a website for them in english - found something in chinese, but not even sure what dialect, and something of a "fred flintstone" website, similiar to Alibaba's, not a lot of detail or info. Couple that with when potential customers on amazon ask about service or if they need parts, they're told to "just all them" with no number provided...??? Other customers asked if it was possible to view the owner's manual for various models, and were told to, again, call in and a CSR would email it. Other reviewers complained or remarked about the poor quality of the instructions in the manual with the unit they'd purchased.
KWS does claim, in one of their responses to posted questions, to be the prime manufacturer of meat slicing machines, supplying most of the other vendors (private labeling). I find that claim questionable as there'd be more similiarity to the other machines being offered.
Then one reviewer posted a couple of pictures, on his $384 model, of the plastic worm drive gears between the motor and blade, with all the teeth sheered off. But his major complaint was when he called in, he was asked to email in pictures to the CSR and "she'd get right back to him" - 2 weeks later, not having heard back, every time he called in again, his calls went straight to voice mail. Call me paranoid, but it sure sounds to me like that CSR rep learned how to use the "block call" feature on her smart phone.
All of the above screams to me to not spend my money with them. I saw it with the Dahua security cameras 2 years back - the two most respected commercial market security cameras are Dahua and Hikvision, and one forum was hyping or shilling for dahua - you'd have thought they walked on water, with review after review on how well their camera (whatever model was being reviewed) performed - i tested Dahua by calling into customer svc - never got a call back. I downloaded their software for the hey of it to see how difficult it'd be to set up - my virus software went crazy, i'd never seen the red flags & alarms on my screen before and haven't since. And they had no US service center - Hikvision did. I bought one of their cameras - had some issues with setting the camera up, called in, got a svc rep right off the bat, totally professional & knowledgeable and spoke US english perfectly. The Hikvision camera wasn't but $20 more than the Dahua camera with the same capability. Oh, and the camera's been doing great (4k resolution) for 2 years, outside installation. I can read a license plate almost 100 yards away. I've not got 5 of their cameras outside.
