Question about Beurer SL 60

I have been using the snoring mask for 10 days now and so far I am not satisfied. The entire operation of the app is very awkward and not at all intuitive, and the data transfer from the mask to the app is also faulty. The intensity of the vibration and the sensitivity of the sensor can be adjusted, but it takes a while to find the best setting for you. The settings only last as long as the mask is connected to the smartphone via Bluetooth, but the connection to my smartphone (iPhone X) has never lasted a night. Every morning the connection is interrupted, I don't know how long it lasts, I was always asleep :-) In addition, the headband is of poor quality and was already warped after five nights. All in all, a good idea but very poorly implemented, as if they hadn't tested the product themselves first! At least the mask is comfortable, but as a pure blackout mask it is a bit too expensive... I will probably send the mask back.

Just my experience: unfortunately no! I ordered it and sent it back after one night. The mask detects vibrations and reacts with vibrations. This brings you out of a deep sleep and, in my opinion, does not lead to a restful night.

In addition, here is my opinion on the service from Galaxus: Thanks for nothing! For a reason that is not clear to me, I have to pay 10% of the value for this return + shipping. In other words, this experiment cost me 17.90. At first I thought I was reading something wrong and said "they certainly don't do that! I thought wrong. I received the bill today. I think it's a disgrace! How else am I supposed to judge this product? I can't access the internet ... Well, this episode will definitely influence my desire to buy in the future.

Setting up the app went smoothly, as did adjusting the mask and its sensitivity. The smartphone does not have to be connected overnight, which I see as very positive.
The fact is that you have fewer deep sleep phases, but it neither prevented me from sleeping nor disturbed me massively. It was very impressive that with the help of the mask I could prove to myself that I was asleep after all, although I thought I was awake. That was good for my soul.
What is impressive is measuring the volume in dB with comparison. Knowing that one's own snoring is as loud as road traffic...
What is pleasant is the complete darkness without touching the eyelashes, which is the case with normal sleep masks and always bothers me.
Clearly not a bad buy for me.
