Review: Faulty lid x 2 - First one arrived next day, read instructions on how to use went to remove lid and soon realised the lid was not going to come off. Child proof lid where you push down and twist nothing just click click on every turn, thought it might be me, so got someone else to try and same thing happened. Returning as faulty and ordered replacement, arrived next day and had exactly the same problem. Conclusion obviously a faulty batch. Returning will not bother ordering again. Now looking for an alternative.

### ⭐ Watch bottle size this is very small and misleading
*by A***R on 25 February 2020*

My fault but why are you selling a 50ml bottle for £12 and a 500ml bottle for £15
