(Mostly) good and (a little) bad
Overall, I'm enjoying my earthing pad very much. I'm sleeping better, my post-workout recovery seems quicker, and just laying on it during the day calms me down.
One bad point is the length (I'm 5'11'): it just fit my mattress, but after a single wash it shrunk a bit (partly my fault I guess) and now it doesn't go fully under my pillow and my arm sometimes catches the edge and the elastic bands at night. Wish it was a bit longer to be able to bend over the top and bottom edges of the mattress.
The other bad point is the cord-pad connection: it's on the top side and I accidentally kick it at night while moving around, sometimes un-connecting it. Seems like a poor design choice. Wish the connector was on the bottom side so the top would be completely smooth.
All said, the two bad points are just little inconveniences, and overall I'm glad to have the earthing pad. It's worth it for sure.
