„I bought this transponder for is convenient installation and low power consumption. It performs as advertised.
Unfortunatly at the end of the first season it started to have an intermittent failure on switching between VHF and AIS mode. I mailed about this to the manufactruer of AMEC (alltekmarine.com) and they promptly offered a free replacement under warranty.
This was executed dilligently by SVB. Email communication by svb could be improved, while email communication and service by the manufacturer was excellent.“
