product is very good quality and they did shipping on time without delay

The device has a great quality/price ratio. It works well, however with 2 défauts that could be improved: - The humidity sensor is too high. It should ignition above say 60%, and it does only after 75% according ro my externat sensor. - The button used for connecting to the mobile Phone is hidden inside. So once the device is mounted, it is impossible to access. I try to get answers from the support. It answers but does not seem to understand the problems so it does not help.
