Optical"AM EAS" Tag - Large Opening - Case of 200 Pcs

We use these in our shop to prevent theft of sunglasses. They also do NOT alarm, we have an EAS security gate and when they were delivered, they did not trigger our alarm at all. They do the job in some ways, but we have had a few that have broken completely. If you tighten too securely, the scewdriver componant will get stuck and won't release from the lock. We have broken a few trying to get it out and have had to basically leave it untightened in order to release the tool. These are really expensive for what they are. They are not reliable or easy to take on and off, very manual and honestly, sometimes embarassing to deal with at the counter while take them off in front of customers. They seem to strip every time you turn them causing white flakey plastic dust to fall away from the component every time you turn it. The only purpose they serve is to prevent theft due to the invonvenience of getting them off the arm of the glasses. I can't recommend them to any retailer without them considering this information. These really are outrageously expensive for essentially a suggested theft prevention prop. If I had paid $30.00 I would be more understanding but buy at your own risk.
