Although this gadget seems to work okay, I have issues with what it is for the cost. Firstly, the instructions are tiny and I needed a magnifying glass to read them. Secondly, there are some glaring omissions in these instructions, e.g. "it is recommended to turn on the heating function button for about minutes" - how many? Lastly, there's not enough explanation - e.g. do you use with eyes open or closed? There is mention of a 'double eye round spray' - I don't appear to have this. Having paid £45 each for 2 devices, (one a gift for my daughter) I did expect more.
Absolutely brilliant my eyes have never felt better! No more dryness.
Not sure yet, only just arrived.
Very expensive without realising l could have bought this for half the price.
So check around before purchase .
At the moment everything is perfect, you have to see now how long the battery lasts, but very happy to the minimum I have managed to listen to the tv at 7 volume when I had to have it at 30 or more!
