These are incredible!

I noticed that smartwatches interfere with the bluetooth communication between the BLS B-Pulses and the smartphone. Therefore if I want to use it with my clients, I need to ask them to remove their smartwatches before putting the BLS on their wrists.
Unfortunately the bluetooth communication with the smartphone/app is unreliable (even without the smartwatches) and the communication can be dropped, causing a variation in the rhythm of the bilateral stimulation, and this can distract my clients from their process.
Positive point : The presets (accessible from the physical buttons) are more reliable and the rhythm can be maintained for several minutes without interruption/dropped beats, which is very interesting. It's unfortunate there are only 5 presets.
The rest : size, wristbands, charging - good :) The option to turn on/off the lights on the BLS is interesting.
Overall, the price does not match the expected quality (esp on the connection reliability). I hope it can be improved in the future.
