This is a HD portable field monitor, and it does a terrific job. Unfortunately, the unit is supplied without a battery. This means you have to order not only a battery (I bought a Panasonic Camcorder Battery CGA-DU21, which does the job) *and* a charger for the battery (deep breath: Ex-Pro Panasonic CGA-DU06, CGA-DU06A/1B, CGA-DU07, CGA-DU07A/1B, CGA-DU07E/1B, CGA-DU12, CGA-DU12A/1B, CGA-DU14, CGA-DU14A/1B, CGA-DU14E/1B, CGA-DU21, CGA-DU21A/1B, CGA-DU21E/1B, VW-VBD070, VW-VBD120-H, VW-VBD140, VW-VBD210 Digital Camera Travel Charger, UK, USA, Canada & Europe - 2 Hour Fast Charge - for Panasonic Camcorder NV-GS150, NV-GS150B, NV-GS150EGS).
A field monitor is useless unless you can use it in the field, and few of the fields I shoot in have an electrical power point conveniently to hand.
You'll also need to buy a hot-shoe mount adaptor if you want to mount the monitor on your DSLR camera.
The instructions are written flimsily in pidgin English.
All that aside, there's not a lot of competition in the field monitor arena, and this (eventually) does the job splendidly.
