Electrodes:
According to the manufacturer, the electrode hold up to 30 applications.
After the first use I felt that this could not be true. But neatly packed in their film in the bag, they stuck in re-again as well.
A total of 4 electrodes are in the package. They can reorder here on Amazon as a 3x4 package. I have handled it that I have used for my needs only 2 electrodes. This is also one must not connect, but at least. 2
So the package holds a total of a little longer.
Device:
What makes me pull off a couple of stars, the handling and stability of the device.
(-) The Platsik is simple and fragile. When opening the battery compartment selbiges me is almost broken and I'm already rather someone very carefully.
(-) The connection between cable and Elekrtoden is quite small and fiddly. Someone with shaky hands (or similar) will here find it difficult to join itself. Also for me it was hard to get plugged, because it was quite heavy.
(-) The display is quite large and initially illuminated in blue, but very quickly, the background is dark and the display reflects very. I have noticed often that bothered me this because I could not read what I've set / how far had passed the time.
(+) The electrodes are well packed in its protective bag and reusable.
(+) Everything is stowed in a bag and handy small
(+) Quite good guide. It gives a lot of information.
