I have used some other HoMedic products in the past and liked most of them. This one worked well also. The HoMedic Spa Relaxation Sound Machine has lasted us for awhile. There are a variety of sounds on this machine from the ocean, waterfalls, the rainforest and more. The volume can be loud or quiet. I babysit a little toddler age boy from time to time and when he takes his naps this goes on. It blocks out the noise from what's going on downstairs and gives him a nice long nap to get him refreshed for the rest of the day. I put him down once without it and he woke up in a lot shorter of a time from hearing my other kids downstairs. This is also just relaxing to fall asleep to. I really like that this has a timer on it if you don't want to leave it on all night. You can set the timer and know that it will turn off itself and that it won't be on until the morning. The sounds are nice, soothing and help after a stressful day. I like this product and it has held up for a while. It is made well!
