I was comfortable with our previous Fisher and Paykel pigeon pair and the recess in our kitchen was specifically built to that size. When the old unit stopped working, I thought it was fantastic that we could get the same units but brand new (and so shiny!). Sadly, I wish I didn't as the new units are so annoyingly noisy. I like knowing where everything is as there was no change to layout, they fit the spot perfectly, but I hate the noises they make.
