Gift has a daughter, who appreciated and have served several weeks before you get tired. The lid is screwed but not semboîte which does not allow long-term use, and special attention that it does not turn into a bag to empty it. The bottom unscrews also difficult to include batteries there. Lhélice has inside seems fragile but works well. For prolonged use is better wash it in the dishwasher faucet Cheap, original gifts that will please, but do not expect a gift that will stay!
