Thanks for the response, Dollypop. Sadly, I found one of the chimes on the ground this morning...broken. The guaranteed product I bought from 3M, didn't hold. The only guarantee I received from the company this morning was a replacement of the product, which I declined. (I will take it back to Lowe's for a refund). The broken chimes, they told me wasn't their responsibility. To think, I was so careful with them during my cruise not to break them.
