Query: Worth it

Ive had this for 3 years and just bought a second one. I used it in my baby daughter's room since my husband and i prefer it cooler when we sleep/ This seems very safe and I dont worry about fires when used correctly and it maintains a desired temp rather than just spitting out a ton of heat. it is really compact too so youd never notice it in a room. it is also very quiet and the sound you hear is very subtle.
