Frustrated about Venu 2 accuracy of indications. Is Venu 2 a toy?

I have tried a lot of different smart watches and have found the Garmin to be very reliable and accurate.  I find The Quantified Scientist on YouTube does some really good testing with smart watches.  He tests all the major ones, maybe there is another one he has tested you will want to try.  

Here is the Venu 2 tests:

First of all,  thank all of you for replying. I appreciate that you shared your time and thoughts here.

CindiL exactly this test was decisive for me to choose the successor of 3 years old Amazfit Bip. But Quantified Scientist hasn't mentioned anything about body battery,  stress level or barometer and thermometer precision. But he showed that sleep tracking is good enough.

- I know,  that stairs and floors may differ everywhere,  but why climbing three floors in the same building causes Venu 2 to show sometimes 0,  sometimes 2 , sometimes 3,  sometimes 12 floors climbed...

- Sleep tracking is for me important so I thought that a watch 5x more expensive than Amazfit BIP should be more accurate than cheaper BIP.  But the chart of sleep phases,  even hour of failing asleep and awakening is erroneous.  Second thing is no support for Sleep as Android,  there's an application in Garmin Connect to do it but it is so unstable and battery draining,  that it's useless.  In cheap amazfit BIP and application Notify and Fitness the support for sleep tracking was a way better,  also an Android app Sleep as Android was supported and worked flawlessly.

Things like stress level or body battery are in my experience random and have 0 value in real life for me.

About pulseoximeter I can write the same,  I'm laughing seeing breathes rate per minute or saturation percentage. 

I can agree that GPS and heart rate sensor are better than in BIP.  I love Garmin Connect app and I appreciate its developers,  but tons of algorithms should be corrected. But I really count on more accuracy of data.

Yes,  I know that's only wirst device,  not professional,  but if somebody sells a product in the market,  should be responsible for specification.  There's no explanation,  that body battery,  pulseoximeter,  barometer,  thermometer,  accelerometer,  are experimental. So user can count on good,  sufficient precision in real life.

Well,  I decided to give Garmin second chance and returned my watch for replacement.  Maybe it is defective. Let's see.

Hoping that Garmin will release more updates to firmware,  there are rumors about Venu 2 Plus,  I hope that Garmin will not abandon Venu 2 then. 

It's suspicious for me they are releasing Venu 2 Plus so fast.  May Venu 2 hardware be defective and they must start to sell corrected model?  I don't know,  we'll see.

You’re right, the Venu is very expensive.  I’ve had the Venu SQ at half the cost for over a year and decided to upgrade.  The Venu 2 has a better sleep tracker then the SQ but I actually found it to be pretty accurate.  

One thing I’ve noticed about floors is if my hand is on the railing, it doesn’t count them.  It only counts them if the hand with the watch is swinging free.  But I do agree it misses them quite a bit!

Pulse OX is better on the Venu 2 then the SQ but I press the watch firmly into my wrist when doing it to make it accurate.  This won’t help if you’re measuring during sleep though…..

Hope the new one works better for you.

I think the hardware on Venu 2 is good but the software lack of it...they need to fix this

Eventually I returned my Venu2. All of this data seems to be inprecise, quite volatile and there is not enough support to actually understand what the fluctuating HRV, health snapshot results etc mean... Yes there are plenty of pages to read into. But I would just like to get a clear message from the watch. Now since the data is sometimes completely different even when doing two health snapshots one right after the other one has to wonder if these data are reliable at all. 
And funny enough, I got more stresses out when the stress indicator showed me high stress although I woukd not actually feel stressed at all :) 
That is probably not the main idea behind it 

The reporting data of data on this Watch is in accurate I have had other brands to include other Garmin watches and unfortunately the venue 2 Has yet to give an accurate read on any of my workouts. 

It counts hills as floors too, so basically it measures ascent and descent and gives them to you as floors.  When I go on walks I go up a big hill and it usually counts it as about 10 floors.

I ended up returning my Venu 2 because it really wasn't doing anything that I'm interested in any better than the FR645 that I've been using for the past 4 years. Step count, floors climbed, resting HR were not any more accurate from my observation.

One thing to keep in mind though if concerned about the heart rate monitor accuracy, is this line from dcrainmaker's excellent in-depth review of the watch: "The optical sensor is on 24×7 to measure and record your resting heart rate. Then in workout mode more power is supplied to it, to handle the challenges of tracking your body bouncing around." In other words, the HRM is more accurate when you are actively recording an activity. Later he does a detailed accuracy test while running and biking, and it's really quite good.

This is true, for instance I have my HR set to “smart” when not in an activity, but during an activity it takes the HR every second.
