    I’ve been trying this device for a few days. It works for some very specific use cases. It does not produce substantial EMF’s as it has no BlueTooth or wifi. It requires no smartphone or app and does not present privacy concerns with an app provider monitoring everything you do. It provides clock, steps, distance, calories, and a manual sleep timer. Note that any device that’s measuring calories without an accurate heart rate count is only giving a gross approximation for an “average” person of the gender and weight you enter and “average” walking. Even with heart rate, it’s an approximation. This device does not measure heart rate. High accuracy calorie counting requires treadmill / oxygen use testing. As such, I don’t care about the calorie counter.I was mainly interested in step counting. If you input your accurate stride length, your distance numbers should be good IF the step count is accurate. Note that this is NOT a GPS device. The problem is that the step count is frequently NOT accurate. According to my testing with a manual tally counter (clicker), the device records steps while walking for exercise pretty well. It was accurate to within just a few steps out of 100.But, the problem is that it’s not accurate when not exercising. WHAT? you say. It records phantom steps when it shouldn’t, and this falsely inflates the step count. For example, if get out of a chair and go to the bathroom, do my business, wipe my nose, wash my hands, dry my hands, and return to my chair, the unit will record about twice as many “steps” as it should. All that hand movement messes it up. Also, it recorded several hundred bogus “steps” while driving in my car for about 7 miles on common paved roads.The cumulative effect is that the step count, distance count, and calorie count are way too high at the end of the day, assuming I go to the bathroom a few times and drive a few times.So, here’s the only way I can see using this device. Say you are actually going to walk for exercise. You note the step count before starting. Go do your walking. Note the step count at the end. Then subtract the two numbers to get the net, which should be pretty accurate. Otherwise, ignore the step count during the day. The unit has no reset button, but the count resets every night. It does not keep any long term records. I’m probably going to return this and try a belt / lanyard / pocket pedometer from RealAlt.This unit also has a feature where it turns on the display light when you rotate your wrist. That’s OK if you want to read the unit. But, my wife said it turned on during the night while I wasn’t trying to access it. Apparently, this also happens with the sleep timer on. So, this might bother you or your mate while you’re sleeping.If the RealAlt pedometer is not as subject to false readings and / or if I can reset it on demand, I’ll probably use that instead. Based on my reading, many pedometers and fitness trackers, even expensive ones, are subject to these false measurements. If the other one also accumulates false steps, I’ll have to reset it each time I exercise, and the daily and 30 day accumulated numbers will be wrong.Note that comparing one pedometer to another isn’t very useful. The only way to know if one is accurate is to compare it to a manual tally counter where you click it on every step. Or, you can click it on every other step and multiply by two. This tells you if it’s properly counting steps when it should. Then, you can check the pedometer to see if it gives false readings when it should not be counting steps.If you think you can live with these limitations for this unit, it might be useful to you. Otherwise, you may wish to look elsewhere. Note that it is VERY hard to find fitness trackers that don’t produce EMF’s. The Bluetooth and / or WiFi can be turned off on some of them, but not all. Almost by definition, the smart bands and smart watches are going to be pretty dependent on their wireless functions and connection to a smartphone or tablet.Ron

    I have it a 5 due to price and functionality. You get what you paid for. I don’t know if it’s properly reading my steps or anything. I used it for about a week and now it’s in a drawer. I’m just going to get a Apple Watch or one with more functionality features. This is more like a play toy to be honest. The battery life is good. It has a nice look to it. It’s just too basic.

    I purchased this watch specifically to accurately count my steps during the day. Originally my husband bought me a more expensive watch with all sorts of bells and whistles, however I really hate how convoluted they make technology. With this watch I do not have to download an app, nor do I have to be tracked via GPS. I simply make sure the watch is charged and start walking. It is simple and easy to use. In addition to that it is comfortable. The rectangle design and slim width fit perfectly with my wrist. I don’t have any complaints at all. I do recommend this item for digital minimalists (if that is a thing).

  4. Laura Tyler

    Nothing fancy, does its job and doesn’t make it difficult to operate. Purchased for a gift and they use it daily.

  5. Cat Fereday

    I did all the fiddly setting up of the watch and now it doesn’t work. It keeps turning the ‘sleep’ mode which means it does not count any steps. This morning, I’ve apparently only taken 21 steps from when I put the darn thing on at 9am to noon, and I’ve been running around all morning. It’s a complete waste of money and – more importantly – of time!

  6. Shauna Pele

    Straightforward watch no messing with an app. Easy to charge just plug into computer. Easy to set up. Comfortable strap looks expensive and actually so cheap. Really happy with it to have time and step counter.Only thing is didn’t read my sleep hrs at all and wore it all night

    This little watch with step counter arrived 4 days ago, so it hasn’t been in use for a long time, but I like it. If you’re just looking for something to tell the time and give you a general idea of the number of steps you have for this day, and you don’t want to spend a lot of money, you might like it too. It took me 10-15 minutes to set up and as said, it gives you a general idea of how many steps were taken. If you are looking for a very high degree of accuracy, you might want to spend more money, but if you just need a general idea of how much walking you’ve done, you might like this too.

    I didn’t want a watch with an app, just a simple watch to count steps and tell the time. This watch does have other features though. Seems accurate as measured against others pedometers. Simple to set up. The watch detaches from the strap quite easily for charging in any USB socket. the feel of the strap is nice – quite soft.

    After buying, trying, giving up and returning two Fitbit watches (a luxe and an inspire 2), I was cautious to try again with this watch. But I am surely glad I did. This GRV FITNESS TRACKER doesn’t need an app, doesn’t need Bluetooth and best of all it just works…unlike either of the fitbits. It is well designed, charges easily, quickly and holds a charge. The screen is easily legible in bright outdoor light. The watchband is comfortable and attractive. I wholeheartedly recommend this 5star++watch. I was reassured to find a product that actually works as promised…this is it.

    Bought for a child that like to keep track of steps. The battery last about 3 to 4 days before needing a recharge. With average 10k steps per day

  12. JAN

    After only a few days the counter is losing a minute. As a very senior citizen I cannot figure out how to correct the time. Actually had family member set it for the time change and set it two minutes early.It is already one minute late. Oh well. I will wear my watch too.

  13. Floristjune

    I love the style , the ease of use , that there’s no app or Bluetooth required and it’s comfortable to wear.The bad thing is I don’t think the step count is accurate, this morning when I got up went to the bathroom and back which is 15 steps each way so 30 in all the watch said I’d done over 300 can’t remember exact number. Maybe I’ve done the step measurement wrong I will have another go at doing it . If I can solve this problem and get it to count properly then I’ll be happy and well pleased with the watch .

  14. Amanda

    So what’s good. Easy and comfortable to wear. Easy to read with very clear illuminated figures. Battery charges quickly. What’s not so good. A bit fiddly to initially set up. Battery does not last over 24 hours.Sleep function does not work.

    Can I purchase replacement bands?

    Dear customer, the band can be replaced. Currently our shop does not sell replacement bands. Hope this helps you. If you have any question, please feel free to contact us.(Steps: Go to Your Orders>>>Find your order in the list>>>Select Problem with order>>>Choose your topic from list displayed>>>Select Contact seller)

    Can this watch be set to military time? Need that function for work.

    I cannot be sure. The answer to this question would be: When you set your time on the SETTINGS,--merely set it to Military Time? That might be the solution. All I can tell you is,---that,--I LOVE THIS WATCH!!!

    How does sleep monitor work? Does it count time as soon as it’s turned on? Or sensor if you are in sleep or not?

    Dear customer, this watch can only record the total time you have slept. And you need to turn on/off "Sleep" function manually. This is the setting steps: Short press the circle button to the "sleep" interface, then please hold on the circle button for 3 seconds. (You can short press the circle button to turn on/off the sleep mode) You can select "ON" to enable the sleep mode, then hold it again to exit the sleep mode. At the same time, there will be a moon icon on the page of this time display. When you wake up, you can select "OFF" to disable the sleep mode, then you can get the sleep time. Hope this helps you.

    Can you set it so that the screen doesn't keep turning on all the time? I'd rather just push the button when I want to see it.

    if it’s been sitting quietly (off) and you kind of jerk your arm, it may turn on very briefly - the person I gifted it to didn’t say it could be set to remain off but she did indicate as a rule she pushes the button when she wants to see something

    Do you happen to sell any bands that are Shimmer or glitter?

    Dear customer, we don't sell shimmer or glitter wristbands. Hope you can understand. Have a good day!
