It has everything I was looking for:
- An ultra compact size that allows it to carry everywhere
- It operates on battery or AC
- The proposed 3 songs are quiet, gentle and without words, perfect to promote sleep (tune of "Twinkle Little Star ah you" in particular).
- There is a projector, swivel (that is ultra-convenient), with 3 different drives (those that are not used are stored in the device; no risk of forgetting)
- The possibilities are many:
you can just put the projector (sheep / fish / moons) in 2 different brightness levels,
just the music or noises (heartbeats, ocean, rain) (adjustable volume)
or not program the time (up to 60 minutes per 15 minutes)
The design is austere but it is the most practical. Nothing to do with the pilot push button, single, non-adjustable music and pretty but not adjustable projection I had until then.
I asked because my sister used it and is also very satisfied.
