"It’s been great for balancing strain/recovery/sleep. ... so having Whoop tell me which days I should go harder or lighter has made such a difference in my training regiment!"
"I do like the sleep metics. ... It’s not as simple as “did I sleep well” or “did I get enough sleep”. To me anyway, actual numbers are more informative. ... And keeping up with the journal helps — I found that my sleep was generally worse on work-from-home days, for example. Then I could modify and be sure I was active during the day."
"I’d say the behavior journaling/insights is a killer feature that distinguishes whoop from its competitors. ... a ton of whoop users reduce their alcohol consumption substantially because this feature is great at showing you how alcohol impacts recovery. in money saved on booze, whoop probably pays for itself for a good chunk of its users."

"Additionally Whoop is simply comfortable to use 24/7."
"And I particularly like wearing it for weeks without taking it off."

"It’s really the whole scoring system I pay attention to. Not just sleep. I use it to adjust habits. ... - I’ve reduced drinking to only a few times a month. ... - I have added magnesium before bed for deeper sleep ... - I move rest days around if I need to if readiness is low ... - I add in extra cardio if the activity goal suggest more movement"

"wireless charging while in use"
"The charging is on-wrist which is amazing for consistency. If you never take it off, you never forget to put it back on."

"Support had me go through all the usual troubleshooting steps — no fix. ... I was told a replacement had been “processed” and would ship. ... It’s now been nearly two weeks and my order is still showing as “processing”. ... I’ve exchanged 24+ emails with Support. The replies are all scripted apologies and vague “please wait” responses. ... Their site promises 3–5 days for new orders, yet for a replacement I’ve paid almost $500 for, I’ve received nothing. ... I’ve asked for a refund policy and escalation, but I keep getting ignored."
"Ecovacs has the worst after sales of any company in any place of the world I have ever experienced. ... The company won’t take responsibility and goi around in circles. ... They wasted more than 6 months after talk to multiple people and site visits and it was escalated till the head of the after sales who I will name clearly: Tanmay Gangani, who is an absolute unprofessional and blatant liar with no sense of responsibility and ethics."
"I have never faced such a horrible service from any products in my life. ... Their service is ridiculous. ... The technician would come home and then inspect the device and raise a ticket for the spare part. So the spare part will be couriered to the customer directly after 2 or 3 weeks. Once this reaches your home, the technician will come again and replace that part. This is ridiculous. ... They don't provide service, they don't provide warranty. ... n one of my friends case, they had denied warranty saying there is fungus on board and its caused by water damage."

"The thing whoop is giving me is wildly inaccurate HR readings. ... Did a casual bike ride with my child yesterday afternoon and whoop gave me a 187 high HR. This was a really slow like 4 block bike ride. ... AW said 108hr peak. Ive biked hard, ran as hard as possible doing max HR tests with my H10 chest strap and never hit above high 160s. ... Im not sure whats going on but its been doing this type of odd HR readings all week."
"I had Whoop for three months and it started showing a very bad data. Like catastrophicly bad. ... Bought Polar chest strap to check my HRV, it was VERY different and was showing me my normal data, data that whoop originally showed to me as well until three months into use it stopped."
"HR reading on Whoop are known for being absolutely aweful. ... Better having an accurate reading every 5 minutes than multiple bad readings every seconds. ... Whoop has awesome software and data analysis, but makes it somehow unusable because of bad hr data in. ... If HR accuracy is not a problem for you, and only follow "very general trends", yeah Whoop is a cool product. But if you are at some minimal point serious about HR accuracy, for real sport / performance / improvment, you cannot relly on it. ... If a Polar device, Garmin, apple watch says it's at 80 with readings every minute or so, and whoop says 65 every seconds, your "constant readings" are not worth anything. Garbage in, garbage out. ... Even counting it manually with a timer and my finger on my neck would be more accurate. ... their linear HR sensors are poor quality, and not the ideal way of positioning them (VS circular patern)."

"the muscular load, the cardio/muscular split, and the intensity didn’t match my perception at all ... and it doesn’t show history/trends per exercise or velocity ... I stopped using it completely, waiting for them to release improvements (which never came - then I cancelled my membership). ... Currently, I don't see how the whoop strength trainer would be *useful* for strength / hypertrophy."
"HRV isn’t a reliable metric of readiness for strength training, to adjust your strength training sessions on a daily basis, based on the current overall body of research ... that wouldn’t really work if the main goal was to maximize strength (and/or muscle growth). ... For my strength training, I'd basically ignore HRV (and whoop recovery / day strain recommendation)"

"got rid of the monthly subscription too"
"This was the promise: You pay for a super-expensive subscription. You don't get enough value for it every month, but when we upgrade our hardware, you get it for free. ... This is what they did: They created a "slightly upgraded" version and called it Whoop 5. And they also created an "actually, significantly upgraded" version, and they called it Whoop MG. And they decided that the "actually upgraded" version will not be free for the people who believed the company's promise and paid the overpriced subscription for years. Instead, if you want the "actually upgraded" version, you will have to pay even more. ... I can't trust you not to release a paywalled Whoop 6 after I upgrade."

"Whoop pulling the upgrade fee move was the last straw."
01chevysil 1.0honestly not sure why a lot of the reviews here are negative, the only thad thing i could say is the steps tracker but it’s also the beta version🤷🏽♂️and im not really worried about steps. I highly recommend whoop to everyone so welcome to the team💪🏽
3820096369 1.0My HONEST review of the 5 MG. So to start with, I'm not an athlete, I go to the gym every now and again, and try to stay fairly active. What I am... is a tech guy, a stats guy, someone who loves data. Last year, I discovered the Whoop 4 after seeing ads for it on social. I spent most of the year wearing one until I had some health problems in December. I had to have some tests, and one critical piece of information that would have been useful was a baseline ECG reading. I couldn't provide it, and it actually hindered my recovery. That was the day I stopped wearing a Whoop, and bought an Apple Watch. Fast forward to today. My MG arrived a few days ago and I'm now back to all the data I used to love with the addition of an ECG and BP. I'll start with the BP reading. We have a blood pressure machine at home so it was straight forward for me to calibrate the MG. Initial results suggest it's pretty accurate, but time will tell. I'll do comparisons over the next few months. Not onto the ECG. Look.. it's ok, it's not as good as Apple's. It's harder to use, seems to be fairly accurate but can give some odd results if not held very specifically. It does the job for me. Let's talk about the quality of the band and device. The device feels premium, the band and clasp feel cheap AF. Because, let's be real with ourselves, they ARE cheap. The material is cheap. The finish isn't particularly amazing. When third parties produce an MG band I'll be first to try them. The packaging felt cheap, it didn't feel expensive at all. I often keep my tech boxes, I won't be keeping this. As for everything else, the app, the functionality, well yeah it's what I loved before. Now... price. I pay monthly. I pay £39. Is it worth that? No, that's pretty ridiculous in my eyes. Am I willing to pay it? Yeah.. because no other device gives me the distraction free data I crave. Do I agree with all the moaning here and concerns? Yeah, you're all valid, Whoop took the piss and have moved the goalposts. But I'm a sucker for tech, and most of you are too, so even though I disagree with their practices we're all going to fall in line and consume. Let's be honest. Short version: It's a good device, new features are decent, it's overpriced but unique to the market.
AD2446 1.0I remember buying my whoop 4 and watching all the reviews beforehand. Every video told me that the new model will be free of charge. Decided to buy the whoop, knowing the whoop 5 will come out shorty. I’m cancelling for sure
AdSufficient8464 1.0I just got a Garmin a few days ago. And I use it mainly for runs. Need to track pace, cadence etc. I only wear it when I run. I know I probably went overboard with that purchase, but for sleep/recovery etc I use the Whoop. Best combo ever.
Advantageous01 1.0That is the rechargeable battery pack, typically attached when it is off wrist to recharge for a couple hours. The Whoop itself is integrated with the band/strap and very slim. https://preview.redd.it/p5k2ovy62iff1.png?width=2196&format=png&auto=webp&s=7be112a670ae0907ce0aa102cdb1299f822637d9
I believe this is the 4.0
alexisnothere 1.0I wear a Whoop band day to day and put on my good ol fenix 5x with a hr band when I’m out running
ath1337 1.0I got my MG yesterday and don't have any issues with the band and clasp. It locks into place just fine and rotates smoothly when removing the whoop. I guess they had some QA issues for the initial batch. I went for a treadmill run yesterday and used my Polar H10 to compare HR tracking to the MG. It was pretty much in line with the H10 and while I did get some cadence lock at one point it corrected itself in like 10 seconds, which is better than what I was experiencing with the 4.0. It was only one run though so doesn't prove much...
Away-Ad-3717 1.0I mostly play volleyball and lift. Garmin bulky and messing with passing during volleyball Oura used to fall off during volleyball and very uncomfortable during lifting Whoop with biceps attachment fixed all those issues for me
bearkin1969 1.0Having had my MG for a couple of days and run, cycled and lifted weights with it, I can say confidently that it's ability to measure HR on the wrist during activity is just as bad as the 4.0 was. The 4.0 was excellent with a bicep band and I am desperately awaiting my bicep band for the MG. I do think forcing everyone to buy new bands was cynical by Whoop. It would have been incredibly simple to making it compatible with existing bands. Apple have with their watch for 10 iterations.
beeeeeeeeeeeeeagle 1.0Heart rate zone training. Alarm. Keeping track of my week month. Satisfaction in achieving goals. Not so much changing my actions but reinforcing actions and assisting with training.
I do the same. Works a treat.
