How can I tell how many objects I've stored in an S3 bucket?

Unless I'm missing something, it seems that none of the APIs I've looked at will tell you how many objects are in an <S3 bucket>/<folder>. Is there any way to get a count?

Using AWS CLI

aws s3 ls s3://mybucket/ --recursive | wc -l 

or

aws cloudwatch get-metric-statistics \
  --namespace AWS/S3 --metric-name NumberOfObjects \
  --dimensions Name=BucketName,Value=BUCKETNAME \
              Name=StorageType,Value=AllStorageTypes \
  --start-time 2016-11-05T00:00 --end-time 2016-11-05T00:10 \
  --period 60 --statistic Average

Note: The above cloudwatch command seems to work for some while not for others. Discussed here: https://forums.aws.amazon.com/thread.jspa?threadID=217050

Using AWS Web Console

You can look at cloudwatch's metric section to get approx number of objects stored. enter image description here

I have approx 50 Million products and it took more than an hour to count using aws s3 ls
