Hi guys!!! I recently decided to try grounding sheets, but there is just a huge selection to choose from. Each one has different reviews, features, and price tags and I don't know what to go for. One friend got a $200 sheet and says it's great, another bought a cheaper one and seems happy with it too. I would like to understand if there is a real difference in quality and effectiveness or if all of these sheets work about the same. Maybe someone has some personal experience? Share what you've tried and if it's worth overpaying?
