I never write reviews for items I buy, but this product is well deserving of one. I have 2 kids and have struggled with clogging from overproduction. I was miserable the entire time w my first. I would cry regularly bc my chest would just hurt so bad. It felt like rocks on both sides. I tried hot showers, hot rags and would rub and rub with my hands to try and get the knots out. When baby 2 came along, I prayed and prayed I wouldn't have the same issues. Well.. they were worse. I ended up with mastitis. I was so swollen that my lactation nurse told me my brain was not letting my body relax to help encourage the letdown bc I was in so much pain. I could hardly hold my baby bc I just hurt so so bad. A friend of mine showed me this product and it had lots of good reviews and to me anything was worth trying. This massager has literally saved me!!!! Although it doesn't prevent the knots and clogs, I am able to get them out much much quicker and it helps me empty my breasts! I was pumping every 3 hours just to try and work out the clogs. I would have to strain the breastmilk when I would eventually get some out. I am currently working to wean myself to be able to quit. I have been using this product everytime I pump for 2 weeks and I am currently up to pumping every 8 hours and still feel comfortable! This has been amazing for me!!!
