RNIB audible liquid level indicator

Excellent Service.Upgraded to a better unit.When the battery transpired to be dead, replacements were immediately sent free of charge.Very helpful and efficient.Thanks

A great idea and works well but feel it could be modified. I think it should be larger as my father who had sight problems struggles to put it on correctly.

Very easy to use, just put on end of cup and listen to a ring sound and it vibrates.

I've had one before and use it to let me know when level in our water-filter jug needs turning off. We aren't blind or anything but often forget to turn off supply tap without it, with water spillage everywhere. So great gadget!

Purchased as a present for my 89 year old granddad who is blind but still stubborn enough to insist on pouring tea. He i s also quit deaf but he can hear this and it works.

This is a great device. Brought for my dad who is partially sighted and he loves it.

This takes the risk out of pour boiling water and give a little more independence to a blind person. Easy to use, easy to wipe clean

A must for the visual impaired
