I had used this product for a long time in my possession, and every now and then, to me a short time ago due to the eardrum has burst. My ENT was not enthusiastic about this stupid idea itself to flush the ears. Too bad that I had to so painful to know the reason for it.
Stay away from this product! Even if it sucks - goes to the ear, nose and throat specialist at the ears to be flush. Who uses it, should consult definitely times his ENT to!
