Signal quality depends on several factors, including electrode placement, electrical interference, and the user's environment. While results may vary, many users have successfully used this device to monitor sleep stages. | Signal quality depends on several factors, including electrode placement, electrical interference, and the user's environment.

This method involves more DIY effort, but it allows electrode placement around the eyes to collect more detailed REM data. However, keeping the sleep mask or ski goggles securely in place during sleep can be challenging, especially for side sleepers, as the electrodes may shift. This should be taken into account. | This method involves more DIY effort, but it allows electrode placement around the eyes to collect more detailed REM data.

=== Skin preparation === | |||
With the 4 AE + 1 PE setup, little to no skin preparation is typically required, and the electrodes can usually be placed directly on the skin. However, some users may still find it helpful to clean the electrode sites beforehand. In contrast, for the 5 PE setup, proper skin preparation is essential. | |||
To prepare the skin, first remove any excess hair from the electrode sites to ensure optimal contact. Clean the area with mild soap and water or a non-alcoholic wipe, as alcohol-based wipes can dry out the skin and reduce electrical conductivity.<ref name="skinprep" /> | |||
