Review on ENERLITES Countdown Timer Switch For Bathroom Fans And Household Lights, 1-5-10-15-20-30 Min Settings With Manual Override, Always On Blue LED, Neutral Wire Required, UL Listed, HET06A, White, 2 Pack by Seth Wood

This is one of the few switches of this type that uses actual push-buttons and NOT membrane switches. It's intuitive and easy, simple, and does exactly what it should do. Installation was straightforward - I have 4 of them.Update - have been using these for coming up on 2 years, and still love them. One switch had an LED indicator failure not long ago, and the seller promptly replaced it at no charge.These switches are just ridiculously simple to understand; guests have no problems with them. One 'secret' feature that I love is that you can hold down the main button for 5 seconds and the device will turn on indefinitely until you press another button. Highly recommended units.
