I have to admit, I did not buy this for some heebeegeebee spiritual nonsense mystical energy gathering ........ I just bought it to get the kids to the dinner table, to which end it works perfectly.
Through three floors of the house the chimes can be heard loud enough through the kids noise to let them know it's time to come down stairs.
For what I use it for it is perfect and a super purchase. For gathering mystical energy, you will have to ask someone else.
Highly recommended
