We chose Gardena (slightly more expensive) for quality. Unfortunately I was not able to run this probe. As soon as I closed the battery compartment, the probe was not working. The problem is that it creates a doubt as to the quality of the product, while a perfect operation is necessary if one does not want to take risks with his kitchen garden / her plants / shrubs. I chose a trade and I will update my review with the new device. Incidentally, the quality of customer service Amazon with the return label printing.
