i like this bird’s nest. I have been using another bird’s nest for about a year now and eat some bird’s nest every other day. this is very well priced. i use it for skin and feel like it makes an actual difference (as opposed to placebo). i have bought the $790 bird’s nest from local store and i will say it was very nice and larger quantity, but it was more expensive and not really sure more potent. i had to clean it before i could use it because it has feathers. this bird’s nest is cleaner. it is a regular fixture in my health routine the same as co-q 10, ginko biloba and several other supplements i have found to make an actual difference over the years. can see myself using this for many years to come.
