There are not enough reviews on this so hope it helps.
I wish I could compare it to something else, but can't.
I got one because every now and then I'd feel something in my chest, like a palpitation or a strong heartbeat. But I could not tell if it was gas or not.
Now I know a few of them really are my heart, and some are just gas moving around.
Why did I choose Wellue?
a. I don't know who Viatom really is, but I guess they are a reputable company? And Wellue is their consumer arm.
b. It can do recordings RIGHT AWAY without needing to connect via bluetooth to a phone.
c. It can do a longer 60 second recording. Most just do 30 seconds.
d. You can connect cable leads for addition recording options, which include a 5 minute option.
e. It's small/portable/unobtrusive.
f. Built in battery.
g. Can make recordings/save/no additional "upsell" to get to your recordings.
Instant analysis :
Overall, I wanted insight into my heart. Is it really is skipping beats when I think it is? To monitor my heart during recovery after exercising. To train my heart to exercise/relax/exercise/relax...and this helps me. The built in analysis is so-so, but I have nothing to compare it to. Thumbs up as far as I can tell with my short time with it.
My details/experience with it :
1. I've used it A LOT in these past few days. A couple of times I was even lucky enough for it to catch a skipped heartbeat. But in the end, it just says "Regular heartbeat". I guess a skipped beat every now and then is nothing?
2. I've looked at the patterns, and I notice every now and then they look slightly different, like a trending dip here, or a higher peak there. But always just end up with "Regular heartbeat" analysis. Makes me feel the only algorithm/analysis it does is nothing better than what you could also do by eye-balling the EKG recording.
3. The display does seem accurate. It really is my pulse....but I wish you could alter the display size so you can see more of a trend...as it is, you can only see i think 3.5 seconds at a time.
4. You don't need a phone to do a recording. That's one of the key reasons I bought it. Yes, you can transfer data to your phone or PC, but I wanted to record RIGHT AWAY WITHOUT ANY BLUETOOTH CONNECTION FUSS, especially if you notice something. I also use this when I exercise. I do short intervals, and pop this out to see what is happening to my heart during recovery...of course this gives me a lot of "fast heart rate" warnings, but I just want to see if my heart skips beats during the recovery phase.
5. Start up is pretty fast. But when you use the touch-screen to select your options, make sure you are not touching the metal contacts on the device. Often I have my thumb and pointer-finger in place (a natural way to hold) and then my left hand touches to the options on the touch screen don't do anything....so move your fingers away on startup.
6. I like the fact that you could do 60 seconds recording. However, for a 5 minute recording, you need to use the cable leads and silicone gel pads. FYI, I tried to use some gel pads that I used for TENS device. Did not work. The silicone gel was thicker there than for the Wellue. I guess that affected it. Use gel pads with thin layer I guess.
7. You can't rename your readings to make a particular one stand out. Each recording item just shows Time/Date, User, Lead, HR, and it's analysis (Regular heartbeat), and a thumbnail of your EKG. So if you want to mark one and make it stick out, you better remember the Time/Date. You can edit the "user name" and make a note as well, but those will not show when you see your whole list of recordings.
8. You can transfer your recordings to your PC...and keep as many as you want, and can print to PDF, and you can make notes.
9. I tried to do a device "software update", even with the PC app running/recognizing the device, but I just keep hearing the device connect/disconnect. So I don't know what this is about. It should just connect, and tell me if there's an update or if I have the latest firmware already.
10. Display is bright enough to see in day, and darkened to be unobtrusive at night. Audio beeping of your heartbeat while recording only. This is the "Voice" setting (on/off). No beeps on playback of your recording.
11. The charging/data cable seems proprietary. I thought it was a regular Micro USB connector, but it is not. I don't recognize it. So don't lose it. Or order a second one.
12. When connecting via Bluetooth, you can not select which recordings to download. It will download ALL recordings since the last time it Bluetooth-downloaded. So it is best to turn on device and delete recordings if you don't want/need them...then do the Bluetooth transfer.
13. Looks like screen will scratch easily...so get a screen protector.
14. Battery life seems pretty pretty pretty good! I've done well over 60 60-second recordings, a dozen or so 5 minute recordings, and about 30 or so 30-second recordings.. Battery is still above 50%.
