Features the maker’s manual doesn’t mention aren’t listed here, so the clock matcher won’t suggest this clock for them.

A nap timer and a nap wake-up time work differently. The planner keeps them separate.

Without Wi-Fi or a phone

It has no app and needs no Wi-Fi: you set and change everything on the clock, and it runs by itself.

When your child outgrows the light

Purflo Snoozee Sleep Trainer Clock has a sound alarm you set apart from the wake-up light, so it can become your child’s alarm clock once school mornings start. When to move on to a kids’ alarm clock.

Check it in your home

While you can still return it, try the buttons you will actually use. These are checks for you to make; we have not tested this clock.

  • Find how to change the times and switch the wake-up light on, then check it shows the light and sound you chose.
  • Check the brightness, the volume and where the clock stands, using the maker’s placement advice. Check what the lock stops and which buttons still work.
  • Use the clock’s own preview or test, if it has one, rather than unplugging it or resetting it to see what happens.
  • Show the other parent, a grandparent or the sitter the buttons. Read what to do after a power cut before you need it.

Agree on what the light means and what to do if it does not come on, then keep the manual or the maker’s help page with your plan.

Show your child what this clock’s light means, and leave a note for the sitter.

If the light does not come on, check the time, the mode and the power before you reset the clock.
