not accurate at all, even after the long "break in period"... bought a different pellet gun and I am much happier

When I first received this I was pretty thrilled. I've always guesstimated doneness and got a great feel for it but I needed this if I wanted to be consistent. The readings were pretty spot on but after only a couple months of use I'm getting erroneous readings consistently. The thermometer appears to be reading 10-15 degrees lower than the actual temp of the meat. For example, I cooked 3 chicken breasts last night and each one kept reading around 145-150 degrees. Given how long they've been on the grill and how firm they were, I pulled them off and let them rest. They were absolutely well done and I know that the temp was at least 170 given how firm and dry the meat was. So I may have gotten a dud but I guess it's only $10 so I shouldn't be surprised. Furthermore----check out how they spell "steak" the product info page on Amazon. Come on now...

I wanted so badly for this thing to be reasonably accurate, as I really like the backlight for reading the device at night. But alas, the humidity accuracy is just awful (I have an older, very accurate device to compare it to). Temperature isn't so bad; it runs 2 degrees low which I could live with. But humidity runs consistently high by 12 to 13 percentage points - not even close to accurate. Stated accuracy in the instructions is "+/- 8%," so even expected accuracy isn't that great. Maybe I'm expecting too much from a device that's made in China, I dunno.  At any rate, it's going back from whence it came.

Returned. It works, the amount of food seems consistent, it's just completely inaccurate. We feed our cat small portions multiple times throughout the day; with this product we would have to feed the cat once or twice at most. Our cat food is Royal Canin Adult HP, small pieces, http://amzn.to/2bJDFnD and, even on the smallest 1/8 cup setting, it always output 1/4 cup amounts. If there were an option to block half the section on the conveyor belt, or get a different belt, or a 1/16 portion size (meaning 1/8 portion...), or it were accurate with this food, it would have worked out. We filled it up and set up the schedule and prepared the conveyor then let it dump on its own into many small bowls to test it out. After 3 portions, it was apparent that it didn't dispense the correct amount--all were twice the desired and configured amount. After a dozen or so we decided that it was consistent (consistently wrong, though). We didn't own it long enough to comment on timing or reliability, it worked fine in those respects for the first day or so. I would give it 2 stars but the amount was at least consistent, just inaccurate wrong for our cat. Every feeder we've tried has been inconsistent.

Not so accurate.  Varies by about 1.2 pounds upon repeat weight-ins.  Don't really trust the measurement any more.

I'll start this review by saying that I have another Sous Vide circulator, but wanted to pick this up to have a spare for larger batches. I'll be sending it back to amazon for a refund as soon as I can.

1. This thing is not accurate at all, as you can see from my photo. It constantly read between 3 and 8 degrees high, meaning you'd be eating under-cooked, potentially dangerous foods. Not only was the actually temperature off, but the heater would continue to run after the set temp was reached, causing the water temp to over run the set temp by up to a full degree. That means that even if  you're using an external thermometer to monitor your water temperature, you still cant trust this circulator to perform well enough.

2. It's also extremely loud when running. It gives off a high pitched hum, akin to an old CRT television, and visibly vibrates while running. My other circulator is almost completely silent despite having a higher flow rate.

3. The numeric display is dim and the set and start buttons are impossibly hard to discern. They appear to be lacking any sort of diffuser over the LED, so while you can tell that there's a red or blue light flashing at you, you can't tell what the icon is supposed to mean. I finally looked at the Amazon photos and figured out that the bottom one is a play icon and the right side is a stopwatch.

If the Travellortech Sous Vide circulator is your first experience with sous vide cooking, it will also probably be your last. Spend a few more dollars and pick up a circulator that actually performs properly.

The barometer/altimeter definitely have issues with accuracy. I have access to gov't certified barometers at work, and this watch is nowhere near. Even when recalibrating the watch to the known values, it tends to drift off quickly. The temperature function is useless except to measure water temperature when submerged or for ambient temperature when not worn for over a half hour, and then still not accurate. The tide charts are off by over an hour for my location. All of the default's are set to non-US standards. And the compass is off by about 45 degrees. I would not recommend this to anyone.

Yes I too made the mistake of purchasing one of these.  Wildly inaccurate.  Mine had to be set to 50 to equal 70.  Anything below that and it wouldn't even turn off .  I adjusted the limit screws and it is better now but not trustworthy.  It's another typical piece of junk from China.  Zero quality control on something that is kind of important.  Buy something else

Takes way too long to give the temp and is clearly not accurate.

It really isn't accurate. Sure, once you count all the money and then double check it, it seems to know, but it's a 50/50 chance it'll be right. Whats the point of using it if I still have to count it all myself? Should've bought a better one. Great if you just "generally" want to know how much you have, but forget accuracy.

I bought this about a month ago.  It was accurate at first.  Then yesterday, when I cleaned the tank, I moved the probe.  I didn't drop it, or yank on the cord, just gently moved it.  When I put it back the temperature read ~4 degrees below the true temperature.  I've turned it on and off and replaced the battery, but it's still inaccurate.  Not good.

Having purchases this item back in September I have literally spent months trying to calibrate it, to no avail. Sometimes it won't give any reading at all, at other times it seems to be close but the next test shows that it is out of whack again.

Don't waste your money on this one.

It took less than 24 hours to decide that this band was not worth the money.
Pros:
- Comfortable to wear
- Looks great
- Some nice features (like vibrating with incoming calls/texts)

Cons:
- It does not accurately measure activities. Enough said.

I don't know if it's the band itself or the app associated with it that was the problem, but the whole point (for me) of this band was to measure activity. It seemed to think i was engaging in transportation all night instead of sleeping, and it was way off on the step counts as compared with another app i've used for a long time and found to be very accurate.

Really disappointed.

I purchased these spoons when my vet prescribed a few meds for my dog that were tiny measurements - smaller than my usual kitchen measuring spoons.  If accuracy is important, definitely seek some other measuring spoons!  These are not accurate...at all.  First of all, the spoons are not labeled with actual measurements.  Rather, they are labeled with the words, "SMIDGEN," "PINCH," "DASH," and "TAD," which is not helpful, but the seller has listed the measurements in the product description, so I created little labels for each spoon to know their measurement.  After a couple weeks of my dog on the meds, I felt like the dosage wasn't quite right, so I did my own investigating, and sure enough - they are wrong!  What they claim as 1/4 tsp ("tad") is actually 1/8 tsp; what they claim as 1/8 tsp ("dash") is not an actual measurement - somewhere between 1/8 and 1/16; the 1/16 tsp ("pinch") is the only one that is correct; and what they claim as 1/32 tsp ("smidgen") is not an actual measurement - somewhere between 1/16 and 1/32.

Other than the incorrect measurements and lack of useful labels, these spoons are as described and work for my use (now that I have verified the measurements).

Inaccurate at lighter measurements and slow to adjust when adding to to the scale. I've had it not register anything at all till I get up to half a gm.

Not accurate at all.  Would send back but I do not see the option to return.  I would not recommend unless you have time to sight it in your self.  Kevin

I took this watch up to 10,000 feet three times.  The first time, the altimeter was fine and seemed to function accurately.  The second time I went hiking I noticed the time was way off and the altimeter said I was at 2300 ft when it was 8,000-9,000 feet!!!!  The battery was never low.  I gave it one more shot.  At sea level, altimeter is zero.  Back up the mountain to 10,000 feet and the altimeter never goes above the 2000 ft range.  The altimeter was the only reason I bought it.  I am returning it.
