Bought this for myself and told four friends. Three of them have since ordered. The relief is fast and real. Customer service also replied quickly when I had a sizing question. Highly recommend.
Used to sit with a hot water bottle but this is on a different level. Stays at consistent temperature, wearable, and the vibration feature doubles the relief. No comparison between the two options.
Used the simulator function to show my husband what period pain feels like. He was shocked. Then tried the relief belt myself and felt better in 20 minutes. He apologized for every time he said it was just cramps.
I've tried every heating patch and painkiller out there. This is genuinely the first thing that gave me real relief within 15 minutes. Wore it to work and nobody even knew. Ordering one for my sister.
Almost used it wrong at first. Read the instructions on the second try and it worked exactly as described. Heat kicks in within 3 minutes and cramp relief follows within 15. Really effective product when used correctly.
