When unpacking, I was surprised only once on the minuteness.
Perfect for pocket or shirt pocket that you just can always have with us.
Triggering the remote control mode of my Canon EOS 600D works at close range super.
Longer distances I have so far not tried because I felt exclusively to contactless triggering.
If it were not so incredibly difficult to find the focus point pressure it would get 5 stars.
That's the only criticism, to get over there for me, I focus mostly manually.
Who mostly uses the autofocus on the camera needs to focus otherwise he will not be happy with.
For the small price you may just not expect miracles, I have to buy anyway still no regrets and use the remote control almost daily.
