Query: so very disappointed

we had a heated pad for years that finally played out. it was wonderful. wanting to spend less this time than i did for the first one, i bought this item. i wish i had never put it on the bed so i could have returned it. i was suspect when i opened it. poor quality material. poor bed fit. very very warm on the lowest setting. after 3 sleepless nights of feeling the wires, which are quite large, in my ribs--it had to come off. i had rather be cold and i hate being cold.
