These are wonderful and create a great cozy ambience in any room, but they are cheaply made and way overpriced. The battery door is very hard to get off and one of the doors cracked and I have to take it back on, also the base for the large sphere comes loose when ever you lift it up. Hope these last, because I really like them, just wish they were not cheap and junky quality. Also check the measurements because the largest sphere is quite large. The 6 hour timer is nice.
