I just purchased them a couple of weeks ago. I love this product. You can consentrate on jigging and just wait for you pager to go off. The only problem is the batteries and the velcro. I'm going to buy re-chargables so I don't have to replace the batteries. The velcro the give you does not stick well to your tip ups. to fix this, I use hot glue to keep the velcro on my tip ups. Also the velcro on the battery compartment pulls the back off of the transmitter. I solved this by electrical taping the battery compartment cover on.
