COOSPO Bluetooth Heart Rate Monitor Chest Strap H808S, ANT+ BLE HR Monitor Chest, HRM IP67 Waterproof, Use for Running Cycling Gym and Other Sports

Great, Except it Eats Batteries. Over the last ten years or so that I’ve had an ANT+ capable GPS bike computer, I’ve used nearly every HRM strap on the market: the Wahoo TICKR X, several iterations of the Garmin Premium strap, two from Polar, the cheaper CooSpo strap, and this one.Depending on the year, I log about 10-20 hours a week on a bicycle (dipping as low as 8 but usually higher… 2020 was a rough year for motivation with no races on the calendar and everything else going on), and typically have gotten about two years out of a strap before some combination of my corrosive sweat and/or design problems (the TICKR strap seems to like to self destruct due to how the snaps are affixed in the module) ultimately destroys it. During the cooler months, a great deal of this time is on a trainer (which definitely affects how much sweat the straps are exposed to).After destroying yet another Garmin premium strap, I decided to use the other CooSpo HRM strap and it held up… for about a year before it just quit working all together. I hate to be wasteful, but it was less than a third of the price of a Garmin strap so I thought I’d replace it with its bigger brother, the model I’m reviewing here.It’s been about three months since I started using the strap and as far as functionality and fit goes, it’s fantastic. Only the TICKR and Polar straps have any sort of LED indicator to let you know that the device is connected and the CooSpo strap even beeps audibly when it starts up or shuts down.The strap itself, aside from the sensor module, is well made and fits just as well as any of its competition. I would say that the Garmin Premium strap does provide slightly more comfort, but I’m so used to wearing these things that I don’t really notice the slight differences.I use my straps via ANT+ (typically with a Garmin Edge 530, but sometimes with my Garmin Fenix watch) when outdoors and via Bluetooth when indoors (smart trainer with Zwift).I live in a dense urban area in a high rise apartment complex and interference is always a problem (make sure you set up your router to avoid using upper channels in the 2.4 Ghz band if you’re using ANT+) and I will say that I’ve not had to toggle between ANT+ (dongle) and Bluetooth anymore while using this strap.If that was where my experience ended, I’d say this was a fantastic product.However, it seems to eat batteries at an alarming rate.CR2032 batteries, sadly, are Lithium-Ion and while they can be recycled (at a proper facility: electronics stores usually have bins for them) I hate going through more than two a year (across power meters and HRM straps). With almost every other strap, I may replace the battery once or twice a year. Even counting for off weeks, let’s call that around 300 hours (or less than 52 x 10 because I don’t know precisely) per battery (power meters, at least the ones I’ve owned from Stages, Quarq, and Pioneer seem to be more frugal… but I don’t really track those numbers).The CooSpo strap in question has gone through three batteries since I started using it. Three. That’s roughly one a month. The battery it shipped with, which I held no high hopes for, lasted but two weeks before the unit wouldn’t wake up (and yes I tried re-inserting and resetting it per the manual… which is a bit lacking in content, but that’s neither here nor there). After replacing it, I thought that perhaps disconnecting (un-snapping completely) the sensor module when not in use, I might get more life out of a battery (I have noticed that the “shut off sound” doesn’t always happen in a timely fashion when it’s still connected to a sopping wet strap). I may have gotten a bit more life from batteries, but I’ve replaced it three times now.It’s a good strap. It’s a good deal. But for me, the incredibly short battery life is very problematic. I suspect that the sleep/wake loop must be in-efficient (drawing too much current when not in use) or I have a defective unit. Since the last replacement, not only do I remove the unit, but I remove the battery between uses.If you don’t mind going to those lengths (or if I got a dud), then it’s a great deal and offers features only found in straps that cost three times or more. I have never used the CooSpo apps (some users might, though some of them don’t seem to have English text options) and strictly use it for cycling, so take that for what it’s worth.

Perfect for my needs; simple to use and easy to connect. I’ve been struggling to decide what to write up about the Coospo Heart Rate Monitor because I couldn’t find the time to test it out well with any of the recommended apps. I’ve been using it for about four months now and on a near-daily basis and finally figured I’d put down my thoughts on it regardless of not having used any other apps besides connecting it to my NordicTrack 2450 Treadmill. It quickly and immediately was recognized by my treadmill. It very accurately allows the treadmill to adjust my workouts based on my heart rate, and is a marvelous way to optimize my workouts and maximize the health benefits I’m getting from my treadmill. I compared the continuous heart rate readings provided by the Coospo monitor with the information provided by my Amazon Halo monitor and they are always within one or two heart beats apart from each other, but mostly the exact same. So that tells me that both the Halo and this Coospo monitor are spot-on accurate at low to very high heart rates. My resting heart rate is around 60 and my max heart rate is around 170; in all instances and throughout this range, the Coospo has functioned flawlessly.Just for grins, I tried installing a couple of the recommended apps included in the instructions, as well as a couple of highly rated apps from the Android store and, quite frankly, while I mostly had no issues setting them up, I really didn’t find a need for having any other apps. I also didn’t like that they were intrusive and nearly always asked you to set up an account, login ID, password, etc. I have enough accounts and passwords already that I didn’t need anything else. I’m going to stick to just using it for running and walking on my treadmill. If I should decide to go running outside (it’s hot here in Arizona) again, I’ll reinstall Map My Run and try that out.Battery Life: The battery lasted just over three months, which worked out to be about 100 to 120 hours of total use. I noticed that a few times the Coospo monitor failed to connect right away with my treadmill so I figured it was time to try a new battery. Maybe the battery that came with the monitor wasn’t good, but in any case, I find it hard to accept their 300 hour battery life claim. Just make sure you dry the strap and disconnect the monitor from the strap to preclude having the monitor automatically turning itself off, which would run down the battery. This, plus not having a low battery indicator (at least I couldn’t find it in the instructions) was why I downgraded it one star. It’s a great monitor, just wish it had a better way of monitoring the battery life. Oh, PS You can buy 4 to 6 name brand (Energizer, Duracell) batteries for about $5 on Amazon. So if you do the math, it’ll cost you about $5 a year for batteries…not bad for something that does a good job tracking your heartbeat.

It was working …. Update- the company quickly replaced my sensor and so far with two workouts it’s been working well! Will update if it stops again.It worked for maybe 3-4 workouts. I tried. To remove batteries after each workout to enhance battery life and then today it wasn’t working- I replaced batteries and nothing. I made sure the sensors were wet and placed properly and it won’t turn on. Very disappointing as it was working well for the first couple workouts.

Great product and support. This heart rate monitor worked flawlessly for almost a year, using it 2-4 times a week. Connects fast to my devices and very accurate too. I had a few issues and reached out to customer support and they were fantastic and resolved the issue quickly. Definitely worth the purchase!

Device works well. I purchased this device to use compared to a fitbit wrist watch. I was hoping to gather more accurate heart rate data while exercising. I had a few issues the first go around making sure it was sending data to my coospo bicycle computer. I was disappointed at first, buy my mind was changed by their excellent customer service!! They actually responded to me in a matter of hours. I tried it a few more times ( 14 mile bike ride and a 41 mile bike ride) and it works just as advertised. They turned me into a believer and would definitely recommend the product to other users!!
