What is Doctor's Best Sustained Plus Immediate Release Arginine?
Doctor's Best Sustained Plus Immediate Release Arginine promotes a healthy cardiovascular system, enhances healthy circulation and supports heart function. L-arginine has been shown to support the cardiovascular system, through its conversion to nitric oxide. Research suggests L-arginine supplementation may also have positive benefits on athletic performance. Two tablets of Doctor's Best Sustained Plus Immediate Release Arginine delivers 1000mg L-arginine in a bilayer tablet, with two tablets providing 500 mg of sustained release and 500 mg of immediate release L-arginine. This technology allows for enhanced blood levels of L-Arginine for a continuous period of up to 8 hours.

How does it work?
Oral L-arginine supplementation has been shown in clinical studies to support various aspects of cardiovascular health. A randomized double-blind placebo-controlled trial found that six weeks of L-arginine supplementation enhanced circulation and supported healthy heart function compared to placebo. The L-arginine effect was due to its role in NO production. Other clinical trials have shown that oral L-arginine supplementation contributes to enhanced exercise tolerance because of its ability to enhance cardiac circulation and vasodilation of blood vessels. L-arginine enrichment of the diet in healthy individuals was shown to support blood pressure already in the normal range. The overall results of these and other clinical trials showed that long-term administration of this amino acid significantly enhanced endothelial function.

Why take Sustained and Immediate Release Arginine?
The normal aging process in humans has been found to be associated with progressive changes in endothelial function (cells that line the inner surfaces of blood vessels). Research suggests that a major reason for these common changes associated with aging is reduced production or bioavailability of nitric oxide (NO) in vessels and tissues. L-arginine is a substrate for the enzyme nitric oxide synthase, required for the production of nitric oxide in the body. Nitric oxide is a substance critical for the maintenance of normal vascular function. NO mediates a number of physiological effects on the cardiovascular system, including supporting healthy endothelial function, enhancing cardiovascular health and displaying potent antioxidant properties against free radicals.

Wobby? Fixable!
Color: Onyx Black, Color: Onyx Black
After a year and half of excellent performance, the platter became more and more wobbly but the readings were consistent. Finally, it was too wobbly and the readings were erratic. There was no obvious way to try to fix it and I couldn't find any help online. I wrote to Greater Goods customer service. While I was awaiting a reply I could barely see that there was a screw inside that appeared to connect to the back right behind the paper label. I pressed on the label, and it broke through to reveal...two screws! I tightened them both and my scale is back in action just like new! It's ready for years of upcoming service. If your unit starts to wobble, it's almost certainly fixable this way. Oh, and Urmila from customer service just reached out and I gave them the good news.

works great
Size: EK6002
i've had it for a couple of weeks now, and i will say, it works well. calibration isn't in the instructions, but, if you hit and hold all 4 buttons when you turn it on, after it says hello, it will enter cal mode. pressing unit advances to the next screen, which is the auto shut off time. if you turn off the power, or use all 4 buttons to reset it, it does not seem to save, so you will have to purchase calibration weights in order to change it. after setting the auto shutoff, it then lists the 3000 g, which is the max weight. it seems you can change it, but i haven't tried. the next shows random numbers, seemingly the raw value of the scale sensor, then it goes through asking for a 500g calibration weight, and after that, a 2000g calibration weight. the 1000g weight doesn't seem to be necessary. after calibration, the scale seems to do pretty well with the calibration weights. weighing in the center and in the corners seem to be repeatable, although it may be a little off at the very edges or corners. the mat that goes on top of the scale has a hangover on the left side, which helps keep it in place, but it can slide up and down. using the scale to measure liquid, it seems to refresh quick enough to easily allow you to gauge when to stop, although, it may depend on how quickly you pour. one thing to note, the precision mentioned in the description. this scale is accurate to 0.1g from 0-500g, 0.5g from 501-1000g, and 1g from 1001-3000g. this isn't over the weight range of the scale exactly, but rather over the displayed weight. meaning, if you decided to weigh pour over or something, in something heavy (or a collection of things), if you tare out the weight (zero it out to measure the difference), it will still display the first 500g up to 0.1g accuracy. that makes the 3000g limit of the scale much more useful. lastly, this is a rebranded scale...many make the same scale under a different brand. i can't remember which combination of buttons it was, but if you held 2 buttons at the same time, it would bring up a muted speaker (no sound) icon, even though this scale doesn't have sound to begin with. i'm very happy with this scale. the price was good, and realizing that the 0.1g accuracy works up to 500g after taring is great. i used it to measure the water and ice in my 64 oz yeti, to figure out how much water i was actually drinking (got very close to the limit of 3000g).

Good scale to use while making pour over coffee and other things
Size: EK6002
So there is one problem that I have found with this unit so far, but only one, it lags in accuracy slightly. I have used the Timemore black mirror for over a year now and I find this scale to be much nicer in everyway with the one exception. It doesn't instantly measure your pour, it needs a second or less after you stop pouring to give an accurate measurement. It's usually about a gram lag and I have gotten used to dealing with it however you should upgrade your sensor to give a faster reading. Now in every other way I prefer this scale to the Timemore which is almost 3 times the price of this scale. This scale is longer with a larger area to work on making it much more comfortable to do a pour over, also this scale has a solid flat surface where the controls are meaning you will not get water into the controls. I have had it happen more than a few times with the Timemore where if some water falls on the area of the timer or tare switch they stop working temporarily. While making a pour over it is a significant problem when that happens, I don't think I will ever have that problem with this unit because there is no area for the water to penetrate. I do wish the controls gave a beep when you activated and if they made the sensor respond more quickly those would be some nice improvements. However in all for the price of this little scale you can't go wrong, I have no idea how long it will hold up as I have used it for about a month. However if it continues on as it has I see it performing well for a long while, thanks for the great scale and even better price.

Excellent scale in all ways.
Size: EK6002
I’ve used this identical scale for four years, though with a different brand name on it, still identical, made in China with a friendly “Hello” on the splash screen when you turn it on. After approximately 1,000 uses in four years, it suddenly died one day, lost its mind and became obviously useless. When that happened there was no doubt in my mind that I wanted to replace it with exactly the same scale because I liked the old one so much. The controls are logically laid out, the display is bright, it automatically turns itself off after a few minutes if you forget about it. I’ve tested it with standard weights and it’s precisely accurate. It’s correctly sized for its task (a coffee scale), it’s slim, light, has a removable, washable rubber mat that covers the weighing platform, and is altogether a winner in design and utility, and there’s no reason to change anything about it. When this one fails, I’ll be happy enough to buy another. It costs twenty bucks . . .

Simple, does the trick.
Size: EK6002
It's a simple, basic scale. Lightweight, it's easy to move from where I stash it to where I use it for measuring coffee. The unit of measure holds it setting when you turn it off, which is nice. I use it in grams for coffee, which is 95% of my use. I acquired a big bag of coffee (5lbs or so) which I broke down into smaller vacuum-packed bags for storage, measured out at 180g each. The scale mostly performed like a champ, although it drifted off zero twice between during bags. Simply shutting restarting the scale got it back on track. It works for me, if you're a hardcore candy maker or baker, you may want a higher quality unit.
