Weighted Blanket Question

Do any of you have (and use) a weighted blanket? If yes, do you love/hate it? I have been thinking about getting one. Is there anything in particular I should keep in mind before purchasing? I guess an important thing would be that it needs to be washable or have a cover that can be washed. Other than that, is there anything else I should make it a point to know about these things?
