Anyone has experience with chinese finger oximeters?

not accurate for medical use not even close when it comes for the oximeter part

the pulse part might give general idea but not accurate nor trustable

specialy if you have circulation issues the accuracy goes out of window

and it can take long for it to even find something

considering +-5 on heart rate and 10 off on oxy

or even worse :D

source: had 3 of them trashed em all

one of those showed 120 for me right out of the bag ":D"

when real one was 65 or so for pulse

Fug

Aliexpress ones are 11 usd and amazon ones are 17 usd

Is there such a jump in quality in between?

you are better of bying good oldschool blood pressure thing for same price from ali

That's pressure

I need oximetry

i mean you need to dish out easily 20+ for proper oxi

amazon is full of same chinkshit

repackaged

13 usd = about 45 pln

Literally the same thing

100 pln

So you recommend me a proper medical store?

I bet it'll cost 200 pln there

this is one of the better models https://www.amazon.com/Deluxe-SM-110-Display-Finger-Oximeter/dp/B003TJH3LI

That's the one you're using now?

nah but i know for fact that its one of cheaper-good devices

their second generation (sm-165) aint bad either its just even more fragile than 110)

also the plastic does not really handle cleaning alcohols etc

but for home use it should not be that big problem

Added to The List, then. Thanks, mate

but the bottom line is = sm-110 is 1-3 off from oxy and 5-10 off from pulse

at worst

At extremes or averages?

we had like plastic bag (250 euros worth of different shit)

Wouldn't mind it being off by 10 when my bpm is 180, but it'd be a shame if it was wrong at 100

And pulse oximeters generally have a 2% error margin in the ranges of 70-100
