cracking unit for the price, has its own rechargeable battery so it doesn't drain your camera, has a compass as well.If you want to geotag your images, get one of these, better than the nikon unit and far cheaper.

Worked brilliantly for 6 weeks and I was just thinking what good value for money it was compared with the Nikon one when suddenly it went hot and died completely - now I can't even charge up the battery.

Well done all Department/s involved.Would have given a better rating on the Gadet itself if LCD was a bit larger and too, colour screen.RegardsPSVMLT

I have only used for a couple of days of actual photography but it seems to be doing what it needs to do, it would be better if it was comparable with all photo editing software.

Working very well so far. Instruction manual is appalling!

Originally, I was very happy with this. It worked easily on the two days I used it. I tried it again recently and it failed to get a GPS lock then or since... despite clear, unobscured view of sky.

Does what it says on the tin. Not exactly intuitive to use/set up

Very good but it must be fully charged before being used, otherwise it runs the camera battery down very fast.
