@imallears Thank you for replying so quickly. My cats - who reign my home and consider our bed to be "theirs" not mine, would automatically 'veto' anything shaking or vibrating, disturbing their very precious slumber. I much prefer very loud noise vs jolted. No longer purchase from Amazon as they require texting to login/enter code which is not possible without smart technology which I do not have or have ever used. No longer possible to use plain vanilla email login & ordering on Amazon (customer service phone calls were all repeated disasters). Hopefully Amazon does not have a monopoly on very loud alarm clocks!
