Actually I wanted some thing that I would not burst in the microwave or sth was wrong to flee after 10 days etc. I chose that. I like, you can mitigate the heat with the cover provided. By cons, if you forget your water bottle after you have put to heat, no way to "warm up" if it is still lukewarm, not until it is completely cooled - after 4-5 hours .... Also quite heavy but my 5 year old son the door easily, not recommended for elderly people living alone, for example. Be careful with also taken to implement the sidelines, security system cutter so badly positioned so as not to leave unattended, heats after 10mins and is ready for use
