Cold Press Masticating Slow Juicer

Read about pros and cons of 4 main juicer types in Chris Carr book and decided on a Twin Gear type because it was the second best at preserving nutrients; I was okay with the trade-off of being more time-consuming to clean than other types. The most-nutritious Norwalk costs thousands, while twin gear machines cost hundreds. Of the latter, I chose the Greenstar Elite based on reading customer reviews.I appear to have received a defective machine. Amazon is shipping a replacement. I will update my review after it arrives and I've used it for a while.On opening the box, it appeared to have been opened, unpacked and repacked, but nothing was missing, and the parts all looked clean and unused, so no problem, I thought. I read all and followed all instructions (I'm the type that always does that, and errs on the side of treating just about everything from clothing to machines with more TLC than specified). I also watched the DVD.I used the juicer for one recipe from the Carr book on the 1st day (ie, I didn't make multiple batches). Cut up carrots, kale, chard and spinach, I did add one small beet cut into 4 pcs. THRILLED with the results. Juice was delicious. The pulp was super-dry. The machine worked beautifully, no issues. Clean up was not quick. I already expected that and am willing to do it for the benefits. Don't want any speck of organic matter left behind in the screen rotting over time. A helpful multi-tip, multi-brush tool comes with machine which makes it easier to get every speck. Cool so far.I'm a decades long family caregiver, now down to one family member to care for at home. Nutrition has become a challenge. I've had a hunch for a while that the minimal eating has more to do with how tiring it is for her to chew, than lack of appetite. I try very hard to serve her things she likes, and she indicates that what I'd been serving her was delicious, but even with me feeding her to conserve energy, she waves most solid foods away after a few bites. I was aware that she'd keep emptying her glass if I kept refilling it, so for some time, I've been relying on 3-4 nutritional supplement drinks per day to ensure she's getting a minimum of calories and nutrients. But I'm not thrilled, reading the ingredients.She GUZZLED the 1st glass of juice, draining it to the bottom with sucking noises. More fresh vegetables consumed in 5 minutes than I'd normally get down her in a week. VICTORY! YAY!Repeat day 2. I'm elated! I'm excited to anticipate perhaps all kinds of health benefits showing up for her in months to come if this continues!Day 3: I decide I'm going to jazz it up a little and prep some watercress, parsley, and a crisp apple to add to the 3 ingredients I'd used for the first 2 uses. It took quite a bit of time to scrub and cut up, to wash and strip herbs and greens to remove all stems. Looking forward to having her juice minutes away, MACHINE DEAD. Tried other appliances in same outlet, work fine. Tried disassembling and reassembling several times. Tried Reverse button. DEAD. The machine gave no indications that it was failing or in distress the first 2 uses. Worked perfectly. I expect a machine that costs hundred of dollars to be capable of being used once a day FOR YEARS, not twice.As I said, I will update review after receiving replacement and using it a while. The first machine is going back.PS Had to wait til noon Eastern time to contact Tribest Customer Service Pacific time. VERY HELPFUL. GOT MY MACHINE WORKING quickly with over the phone instructions. Back to being thrilled! I cancelled the return and replacement process. Fingers crossed that there will be no more issues. Provided machine is reliable and long-lived, I expect to use this more than our Vitamix. Love it!
