The on-off switch is in the vertical pole on the right. The switch on the one we bought broke in the first month. We managed to get it into the "on" position and leave it on 24/7. Otherwise a good product.
Yes, it has an on-off switch, but no timer. The switch is on the top of the vertical bar and it broke in the first month. We managed to get it in the "on" setting, and we leave it on 24/7 now. Otherwise, great product, wouldn't live in a house without one again.
Yes, we have been using the product for about 6 years. We leave the towels on it 24/7 and leave it on all the time as well because the switch on the top of the vertical bar broke in the first month. Still it has been an excellent addition to our home. Also, the more narrow width made it possible to fit in a very small bathroom over the toilet.
