Any small terminal 22cm x 13cm x 4cm, so discreet, good images, but lonnnnnnng at startup (it reminds me of older boxes + c) count 1mn before obtaining the first image, or let the light ... I constantly compare a 9965HD Balmet that puts 35sec to boot. Otherwise be sure to order AAA size batteries for the remote control simultaneously control of your terminal (mine had no batteries, so have to buy 2 batteries out in order to switch it on). After 48 hours of use to report anything unusual.
