Good Timer with small weaknesses

I have now used the device several times; mainly at night for astrophotography. When you first conceived the end of the settings, the steps seem quite logical. The adjustable shutter speed, the time between shots (Note: is the exposure time + meantime!) And the number of shots make photography easier considerably. So there is enough time to visually observe the Stenenhimmel during the automatic run of recordings.

Sometimes, however, from 2 or 3 seconds meantime not made, especially if the camera is in between save larger RAW files. Then the meantime, must be increased - otherwise the timer arrives at wrong times, because it adheres to the set times.

Among the weaknesses I count the normal long exposure with no timer. These begin with "Hold" printed press key and push upwards. This is done with the thumb - but the force required for this is very high and almost always results in my copy to a slipping of the key without the desired function. - Function does it, if you do not press the Hold button, but moving up with a thumbnail from below! - Also opening the battery door is similarly difficult. Since this is rarely required but, you can ignore it.

For the price it remains a recommendable device.
