I needed this product to exist 10 years ago, this would have been a huge life saver for me. I would 100% recommend the Hottle to anyone who has bad period pains, especially those who suffer from endometriosis such as myself (I also have pcos making the pain more frequent). It is soft, comfortable, and so easy to use. Much better than a regular heat pack as it lasts 3 times longer! I can relax with the Hottle in bed and now I’ve decided to go on walks with my dog wearing it. Thankyou for creating a product like this!
