My husband and I have migraines easily but ever since we received the Blushield Portable, the migraines come and go faster than expected. My mother-in-law had commented that the Blushield had made her sleep better throughout the night and my friend had also mentioned that even though he had only few hours of sleep, he still wakes up feeling better and not as lethargic as before. My friend’s sons are 2 hyperactive kids, but the teacher had commented that they seemed to have better focus during classes now. I put the portable near my toddler during her sleep and found out that perhaps it is too strong for her. So I changed to a Mini and noticed she was able to sleep better throughout the night. She used to have some kind of breathing problem, now it has reduced alot. We realised that all Blushield models had the effect of boosting the sound effects and enhancing music of any kind. Especially when we play techno songs, the bass is much more enhanced and significant.
