I purchased this juicer 9 months ago; and had erred on the side of too much optimism, given it a good review, despite my strong apprehension about dealing with the same company: The Tribest Corp. Alas, honeymoon period is over. I owned Solostar, a single gear juicer from Tribest for many years. It is when I became a more regular user that it began to fall apart; mostly the juicing screen, and later on, I found the cheap plastic augur housing kept cracking as well. As soon as I tried to make warrantee claims; it appears the whole thing must be my fault, at least from the Tribest's perspective; either I'm using it too much (every other day yielding 1 ½ cup of juice), misusing it somehow, or time to buy their higher end Green Star juicer. The new screens they sent me would crack, sometimes after single use; I could detect the hairline cracks along the pressure points that would only get bigger with a few more use. It was a battle every time I had to contact their customer service, and eventually when warrantee expired, I spent more money purchasing parts than this juicer was worth. And they said the parts were also covered under warrantee, except when you try to make a claim. Finally I gave the Green Star a chance, almost $500; a huge investment for me. I took a good look at the juicing screen and the housing; and thought nothing bad could come of these. Well, turned out to be much worse. It's weakest link turns out to be the most expensive part: the twin gear. Just about a month ago, I've noticed the nylon part of one of the gear was splitting, leaving a small gap where fibers get caught. That particular gear has nylon section in two different diameters which are two separate pieces joined together, and probably with stress of use (I believe I am supposed to use it - and twin gear juicers do require more effort) , it had separated, therefore it wasn't a random crack along the nylon, rather separation of two parts. And I am told by service, one of the other woes I can expect from the twin gear is the cracking of the nylon. Well, when I contacted them about this issue, I got a rude response from Service manager, Mario Duenas; quoting history of my warrantee claims from owning Solostar, along with accusations I must be running a juicing business. And initially insisted I should purchase the gear; costing $100. Now, I have a huge quandary before me; the weakest link to this expensive juicer, is the most expensive part: the twin gear. And I have to look forward to next 4+ years of deal with rude, condescending, and downright obnoxious customer service personnel, unwilling to be accountable for their products and warrantee. Obviously I have made a huge mistake in choosing this juicer. Be very weary of choosing products from this company: Tribest Corp.
