Query: Not safe

I ordered this fan and it arrived broken. The propeller flew off which was really unsafe and then it just stopped working. I contacted the seller and they were very nice about sending me a replacement, however, the same thing happened with the second one. The propeller is not attached to the fan so it can fly off and hit you in the face at any time - very unsafe. It could absolutely do damage to your eyes or cut your skin. Besides that it does not provide much wind and goes through batteries very quickly. I do not recommend this product.
