This Dandy Gadget: When we are talking about recorder the first mind line to this gadget is how long we can record using it. This Sony digital voice recorder, ICD-SX850, with 4GB built-in memory can serve you with long enough time for recording, up to 1505 hours.
Although the ICD-SX850 recorder has long recording time, but as its battery only can stand up to 26 hours if you chosen alkaline battery, it’s limited your action except you bring a lot of batteries in your bag.
