Clarification Request
Why here? But to find out, do a quick survey.

I hope you remember your Statistics class where you discussed number of samples and how that told you how sure you were of your answer.

For example you could go to 10 restaurants and if you found 2 then you can write that 20% of the restaurants use this with a margin of error being about 30%. Try 100 restaurants and your margin of error is under 10%

You can find your answer by the end of today with the 10 samples and about a week for the better margin of error.

Then again, you could try google.

Is to do your own sampling. I offered how many samples you need to get your answer within a margin of error but you appear to not be doing your study.

I'm unsure why but some think that such numbers are available but they are not. That is, some get upset that such are only statistically derived and not exact. Because of the cost of visiting all 54 million sites is too much they use the statistic sampling I noted. You can repeat this in a day or week depending on how close your answer must be.

If you demand the answer be exact then you have forgotten your statistics class.

The Samsung RF23M8090SG

One of the best French door fridges we've tested

A good-looking fridge with useful features like an auto-filling water pitcher and a temperature-adjustable "FlexZone" drawer. It was a near-flawless performer in our cooling tests.
