Neutral about it
I've used this on multiple occasions. I've left it on overnight. I also just kept it on for an hour. Haven't noticed much of anything afterwards.

Gift
bought for a friend as a gift on promotion

An okay product
A bit underwhelming for all the hype, but it is a great value compared to the other collagen mask

Nice and hydrating
Nice and hydrating, a bit underwhelmed, considering all the buzz this has generated.

bad
i found it very drying and not hydrating
